RP2040 ETH Mini Dev
Les Pounder loves all his Pi collection, but sometimes there’s some he simply can’t love as much…
Dominated by an Ethernet connection, the RP2040 ETH Mini is full of unrealised potential.
IN BRIEF
Squeezing the Raspberry Pi Pico into a smaller form factor, while packing in USB C and Ethernet, the Waveshare RP2040 ETH Mini looks great, but suffers from poor documentation and overly complex steps to get a project going. Others have attempted to use Ethernet with the Pico, and they have come off slightly better than this board.
We wanted to like this board, truly. Waveshare’s RP2040 ETH Mini distils GPIO pins into the bare minimum, but we are never left asking for more. We’ve got 14 digital IO pins, which also provide access to SPI, I2C, UART and three analogue inputs. Sure, we don’t have every pin from the RP2040, but we sacrifice those for efficiency. Just 47x21mm, this is tiny, with a USB C port at one end, Ethernet at the other.
