Sumolink Erhu RP2040 is a $3.60 Raspberry Pi Pico clone with a USB-C port

Raspberry Pi Pico USB-C port

The Sumolink Erhu RP2040 is a Raspberry Pi Pico clone with the exact same features except the micro USB port has been replaced by a USB-C port that may be preferred by some people, and the Wisdpi claims it is one of the world’s cheapest RP2040 MCU boards at $3.60, although that price does not include shipping. We had seen some other replicas, but most offer something different rather than just the USB-C port. Two examples that come to my mind are the WeAct RP2040 with a USB-C port, but also a Reset button and up to 16MB SPI flash, instead of the 2MB flash in the original board, and the Banana Pi BPI-Pico-RP2040 with an extra I2C connector and an RGB LED. Sumolink Erhu RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash (Note: the specs list […]
