The BPI-Leaf-S3 dev board no longer equips traditional UART TTL to USB converter chip and its dedicated USB port.  This is due to the ESP32-S3 chip's internal USB function were improved, supporting CDC-ACM virtual serial port and JTAG interface, which is capable of software development and firmware management feature, that makes the external converter chip redundant.
 +
 
 +
Compared to ESP32-S3-DevKitC-1 dev board, the BPI-Leaf-S3 adds an external battery socket and a charging circuit, capable of charging the battery via USB. When a 3.7v battery is connected, unplugging the USB will not cause the program to break, making it fit for multiple applications.
 +
 
 +
BPI-Leaf-S3 dev board is equipped with an I²C 4 pin dock, this stabalizes connection to other I²C peripherals.  This dock is not only restricted to I²C connection, any module that requires a 3.3v pin, a GND pin, one or two data pin can also be connected to the Leaf-S3 via this 4 pin dock.
 +
 
 +
==Espressif ESP32-S3==
 +
 
 +
ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. Compared with ESP32, it supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache.
 +
 
 +
What follows is a description of the most important features of ESP32-S3.
 +
 
 +
* Wi-Fi + Bluetooth 5 (LE) Wireless Connectivity: ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g/n) with 40 MHz of bandwidth support. The Bluetooth Low Energy subsystem supports long range through Coded PHY and advertisement extension. It also supports higher transmission speed and data throughput, with 2 Mbps PHY. Both Wi-Fi and BLE have superior RF performance that is maintained even at high temperatures.
 +
 
 +
* AI Acceleration Support: ESP32-S3 has additional support for vector instructions in the MCU, which provides acceleration for neural network computing and signal processing workloads. The software libraries for the above-mentioned optimized functions will become available very soon, in the form of updates to ESP-WHO and ESP-Skainet.
 +
 
 +
* Rich Set of IO Peripherals: ESP32-S3 has 44 programmable GPIOs, namely 10 more GPIOs than those of ESP32. ESP32-S3 supports all the commonly-used peripherals, such as SPI, I2S, I2C, PWM, RMT, ADC and UART, SD/MMC host and TWAITM. In total, 14 GPIOs can be configured as capacitive touch input for HMI applications. Apart from all these peripherals, however, ESP32-S3 is also equipped with an ultra-low-power (ULP) core that supports multiple low-power modes in a variety of such use-cases.
 +
 
 +
* Security:ESP32-S3 provides all the necessary security requirements for building securely connected devices, without requiring any external components. It supports AES-XTS-based flash encryption and RSA-based secure boot. In addition, ESP32-S3 has a digital signature peripheral and an HMAC module, which provide functionality that is similar to the hardware secure element, thus protecting the private or symmetric key from software attacks and identity theft. ESP32-S3 also has a “World Controller” peripheral that provides two fully-isolated execution environments, which enable the implementation of a trusted-execution environment or a privilege-separation scheme.

The Banana Pi BPI-Leaf-S3 is a series of low-powered microcontrollers designed for IoT development and Maker DIY board.It supports 2.4 GHz Wi-Fi and Bluetooth® LE dual-mode wireless communication, the peripheral is compatible with low-power hardware design, and the power consumption is only 10uA in deep sleep mode.

The main controller supports two power supply inputs: USB and external 3.7V lithium battery, both can be interchangable freely. The battery could also be charged while USB is plugged in. Compact size, various interface, easy to use, and can be directly applied to low-power IoT projects.

In terms of programming, the Leaf-S3 supports ESP-IDF, Arduino, micropython and other methods.

The IO pins on BPI-Leaf-S3 are identical to the Espressif ESP32-S3-DevKitC-1, developers can add peripherals that are supported by DevKitC-1 onto the BPI-Leaf-S3, and can also combine it onto a breadboard.

  • In-packge PSRAM 2MB
  • Ultra-low power 10uA
  • 2.4G WIFI ，Bluetooth 5 ，Bluetooth mesh
  • GPIO , ADC , TOUCH , PWM , I2C , SPI , RMT , I2S , UART , LCD，CAMERA ，USB , JTAG
  • 1* SH 1mm 4-Pin Socket, support I2C
  • 1 * USB Type-C

ESP32-S3-DevKitC-1, BPI-Leaf-S3 Comparison

Dev Board BPI-Leaf-S3 ESP32-S3-DevKitC-1
GPIO Pins 36 36
3.3v Pins 3 3
5v Pins 1 1
GND Pins 4 4
ARGB LEDs 1 on GPIO48 1 on GPIO48
Chip Internal USB USB-C Connector x 1 MicroUSB Connector x 1
UART TTL to USB None CP2102-MicroUSB Connector x 1
External Battery Socket 3.7v Li-ion Battery dock None
Battery Charging 500mA Charging Current None
JST SH 1mm 4-Pin Socket 1 None

The amount, numeric order, and spacing of IO pins on BPI-Leaf-S3 are identical to the Espressif ESP32-S3-DevKitC-1.

The BPI-Leaf-S3 dev board no longer equips traditional UART TTL to USB converter chip and its dedicated USB port. This is due to the ESP32-S3 chip's internal USB function were improved, supporting CDC-ACM virtual serial port and JTAG interface, which is capable of software development and firmware management feature, that makes the external converter chip redundant.

Compared to ESP32-S3-DevKitC-1 dev board, the BPI-Leaf-S3 adds an external battery socket and a charging circuit, capable of charging the battery via USB. When a 3.7v battery is connected, unplugging the USB will not cause the program to break, making it fit for multiple applications.

BPI-Leaf-S3 dev board is equipped with an I²C 4 pin dock, this stabalizes connection to other I²C peripherals. This dock is not only restricted to I²C connection, any module that requires a 3.3v pin, a GND pin, one or two data pin can also be connected to the Leaf-S3 via this 4 pin dock.

Espressif ESP32-S3

ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. Compared with ESP32, it supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache.

What follows is a description of the most important features of ESP32-S3.

  • Wi-Fi + Bluetooth 5 (LE) Wireless Connectivity: ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g/n) with 40 MHz of bandwidth support. The Bluetooth Low Energy subsystem supports long range through Coded PHY and advertisement extension. It also supports higher transmission speed and data throughput, with 2 Mbps PHY. Both Wi-Fi and BLE have superior RF performance that is maintained even at high temperatures.
  • AI Acceleration Support: ESP32-S3 has additional support for vector instructions in the MCU, which provides acceleration for neural network computing and signal processing workloads. The software libraries for the above-mentioned optimized functions will become available very soon, in the form of updates to ESP-WHO and ESP-Skainet.
  • Rich Set of IO Peripherals: ESP32-S3 has 44 programmable GPIOs, namely 10 more GPIOs than those of ESP32. ESP32-S3 supports all the commonly-used peripherals, such as SPI, I2S, I2C, PWM, RMT, ADC and UART, SD/MMC host and TWAITM. In total, 14 GPIOs can be configured as capacitive touch input for HMI applications. Apart from all these peripherals, however, ESP32-S3 is also equipped with an ultra-low-power (ULP) core that supports multiple low-power modes in a variety of such use-cases.
  • Security:ESP32-S3 provides all the necessary security requirements for building securely connected devices, without requiring any external components. It supports AES-XTS-based flash encryption and RSA-based secure boot. In addition, ESP32-S3 has a digital signature peripheral and an HMAC module, which provide functionality that is similar to the hardware secure element, thus protecting the private or symmetric key from software attacks and identity theft. ESP32-S3 also has a “World Controller” peripheral that provides two fully-isolated execution environments, which enable the implementation of a trusted-execution environment or a privilege-separation scheme.
