W55RP20-arduino

Overview​

W55RP20-arduino is an evaluation board for W55RP20, a chip that combines W5500, a wired TCP/IP controller, and RP2040. Therefore, both the functions of Raspberry Pi Pico and those of the W5500 are available.

  • Raspberry Pi Pico Clone
  • Ethernet (W55RP20 Hardwired TCP/IP CHIP)
