BananaPi BPI-Uno 32 Board (BPI-A-006)
The BPI UNO 32 (also referred to as BPI UNO 32, stylised as BPI UNO 32) is an ESP32 with Xtensa 32bit LX6 single/dual-core processor based embedded system.
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 PIN Define:
Power supply : Micro USB(Commonly used) or DC 12V Debugging tools : IDE（uPyCraft/ESP-IDF）
Debug method: IDE for ESP32 Program download (Download the HEX file) (Need to add ESP32 board in IDE)
After the program compiles OK, you need to manually press and hold the IO0 button and then use the USB cable to link the card and the PC and then start the download. After the download is completed, release the IO0 button, and power on or reset the program code function normally.
uPyCraft burn firmware and online debugging: When using uPyCraft, you need to burn the firmware beforehand.
First select the interface in the uPyCraft ESP32 board serial port,
Then select the type ESP32, the following can choose whether to erase the flash
When the Download or EraseFlash progress bar can not continue the progress bar after the completion of the need to press down colleagues EN and IO0 then release EN and then release IO0 can be. When the firmware is burned, you need to manually reset the board once it is finished. You can select the serial port connection or click the icon to connect.
After connecting the software in the lower right side of the dialog box >>> logo.
Hardware Interface: Micro USB, DC 12V, compatible with GPIO pin layout
