The BPI:UNO32 (also referred to as BPI UNO32, stylised as BPI-UNO32) ,BPI-UNO32 uses the ESP-WROOM-32 of espressif company as MCU.
ESP32 is a single-chip solution integrating 2.4 GHz 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 240 MHz, 448KB ROM, 520KB SRAM.

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