Banana Pi BPI-ESP32 Board Follows Arduino UNO Form Factor, Works with Webduino and Arduino IDE

SinoVoIP has been pretty busy those days, as beside launching a BBC Micro:bit clone based on ESP32, and BPI-AI-Voice speech recognition board (also a clone or MicroSemi AcuEdge kit), the company has now started to take orders for Banana Pi BPI-ESP32 board for $10.99 plus shipping on Aliexpress.

As the name implies, the based is based on ESP32 WiSoC, supports Arduino shields since it follows Arduino UNO form factor, and can be programming with web based Webduino visual programming IDE, or the Arduino IDE.

BPI-ESP32 (aka BPI-UNO32) board specifications:

  • Wireless module – ESP-WROOM-32 WiFi 802.11b/g/n, and Bluetooth 4.2 LE module; 4MB flash
  • Expansion – Arduino headers with GPIOs, ADC, Ethernet, VP/VB, UART, I2C, Touch interface, etc… (See pinout table below)
  • Misc – Buzzer, Tx/Rx LEDs, power LED, RGB LED, buttons
  • Power Supply
    • 5V/1A via micro USB
    • 12V via 5.5mm DC jack
  • Dimensions – 68 x 53 mm

The company has yet again to make a complete mess of the product launch, as BPI-ESP32 board above clearly does not have any buzzer nor RGB LED, but BPI-UNO32 does have both as shown from the photo below taken from the Github documentation.

Yet they are using BPI-ESP32 and BPI-UNO32 interchangeably in their Aliexpress page. If you are mostly interested in using Webduino with the board, please note that it may only fully work in Taiwan and mainland China:

Webduino service now only provide cloud services in Taiwan and the mainland of China, overseas server has not been set up now, so buy BPI, BIT and BPI: UNO32 overseas clients, only can test and use open source software

It’s not the first time, we’ve seen ESP32 boards with Arduino form factor, as we’ve covered ESPDUINO-32 & TTGo D1 R32 boards last year.
