Udoo Key is a strange-scale T-shaped board, you can see ESP32, powered by dual-core Xtensa 32-bit LX6, 16MB flash memory and 8MB PSRAM, placed on the top of the board, customized RP2040 power supply board is located at the base. RP2040 is the same as the dual ARM Cortex-M0 chip used on Raspberry Pi Pico and many other RP2040 power supply boards, but Udoo Key has 8MB of QSPI flash memory, which is four times that of Raspberry Pi Pico.
The target price of $20 (or $4 if you sign up for the early bird discount) costs more than buying a separate ESP32 and Raspberry Pi Picos, but you pay here for convenience. Both halves of the board are fully programmable and 100% compatible with Pico accessories (this means that the Pico side of the board shares the same pinout as the Pico) and the Olimex UEXT module for ESP32. It supports all commonly used programming environments, such as MicroPython, TensorFlow Lite, and C/C++, and it also supports Clea AI on the IoT platform.
According to the product page, ESP32 and RP2040 can be used alone or together. The real power of this board lies in the use of the two together. How they will communicate, we don’t know.It can be in a similar way Pimoroni’s Pico Wireless, It uses SPI to communicate with ESP32 to provide Wi-Fi for Pico.
