Introduction

Overview:BPI-UNO32 with ESP32
BPI-Bit with ESP32 design

The BPI:UNO32 (also referred to as BPI-UNO32, stylised as BPI UNO32) is an ESP32 with Xtensa 32bit LX6 single/dual-core processor based embedded system. support Webduino ,arduino,microPython,Scratch.x function.

BPI-UNO32 uses the ESP-WROOM-32 of espressif company as MCU. ESP32 is a single-chip solution integrating 2.4GHz Wi-Fi and Bluetooth dual mode. The 40 nanometer technology of TSMC has the best power consumption, RF performance, stability, versatility and reliability. It can deal with various application scenarios.

Two separate controlled CPU cores, the main frequency can be up to 240MHz, 448KB ROM, 520KB SRAM.

BPI-UNO32 The appearance size is fully matched with Arduino UNO R3

Visuino

About Visuino

Visuino is a visual, graphical development environment for Arduino and similar boards, including almost all standard Arduino boards, Teensy, Femto IO, LinkIt ONE, FreeSoC2, RoMeo BLE, Bluno Beetle, Goldilocks Analogue, ESP8266, ESP32, PIC32, nRF52832, Maple Mini, and many Arduino based Industrial PLC Controllers such as Controllino, Bedac, and Digital Loggers PLDuino, and Industrial Shields.

Programming with Visuino is as easy as picking components from the Components Toolbar, placing them in the Visual Design Area, connecting them, and setting their properties with the Object Inspector. The Overview, allows easy navigation over big designs, and Visuino includes built-in Communication Terminal, Scope, and Gauges, and other Visual Instruments to monitor and display the data sent from Arduino. It allows creating complex industrial automation, and IoT solutions by simply dropping and connecting a few graphical blocks. Visuino will automatically generate the necessary Arduino code.

Visuino contains a large set of components for:

  • Math functions
  • Comparators – Analog, Integer, Date/Time, and Color
  • Logic functions – OR, AND, XOR, NOT
  • Flip Flops – T, R-S, D, J-K
  • Switches – Analog, Integer, Date/Time, and Color
  • Generators – Clock, Pulse, Sine Wave, Triangular Wave, Rectangle, Random
  • Timers – periodic or single pulse
  • Counters – Up Down, and Directional
  • Motors – Stepper, DC or Servo
  • Displays – LCD, 7 Segment, touchscreen, matrix, Smart Pixels, and TV Out
  • Sensors – Temperature, Pressure, Weight, Distance, Compass, Accelerometer, Rotary Encoders
  • Remote controllers – Infrared, Servo, Wii or PS2 compatible
  • Date/Time components
  • Color components
  • PID controllers
  • Communication – Serial, RS 485, Wired and Wireless Wi-Fi Ethernet or GSM
  • and many more added daily...

Once the Arduino is programmed, Visuino offers easy way to connect to it over Serial and monitor multiple channels of data in a Terminal, Scope or Visual Instruments:
