This is a prototype board for the Raspberry RP2040.
Main features (if compared to the Raspberry Pi Pico module) is that it has a linear voltage regulator for the 3.3VDC power supply to the RP2040. There is also a 3.0VDC voltage reference connected to VCC_ADC and a FLASH memory.
The USB connector is USB-C type and the board also incorporates both a BOOLSEL and RESET button. There is also an I2C EEPROM connected to GPIO18 (SDA_1) and GPIO19 (SCL_1).
