Compact $2 board offers 24 GPIO connectors and USB Type-C

The WeAct CH32V006F8U6 is a new compact development board that's turning heads in the DIY electronics community, not just for its capabilities but for its remarkably low price point of around $2 on AliExpress.

This tiny board is best understood as an Arduino-like platform, designed specifically for connecting sensors and actuators rather than running demanding applications or desktop operating systems. At its core is a single RISC-V processor clocked at up to 48MHz, which provides more than enough power for typical maker projects.

What makes this board particularly interesting is its I/O configuration. The CH32V006F8U6 features two 12-pin headers, giving users access to 24 GPIO (General Purpose Input/Output) connectors. This abundance of pins provides significant flexibility for connecting external components, whether you're working with LEDs, sensors, motors, or other peripherals. A simple use case might involve controlling multiple LEDs based on readings from various sensors.

The board includes a USB Type-C port for both power and programming. Depending on the version you choose, it can be powered at either 5V or 3.3V, making it adaptable to different project requirements. There's also a debug header for more advanced development work.

Programming the board is possible through an available SDK, though it's worth noting that using the popular Arduino IDE isn't straightforward and may not be possible at all. This could be a consideration for those who prefer the Arduino ecosystem's ease of use.

For those considering alternatives, the market offers several options at different price points. Traditional Arduino boards remain popular choices, as do ESP32-based systems which offer Wi-Fi capabilities. However, the CH32V006F8U6's combination of GPIO density and ultra-low cost makes it an attractive option for budget-conscious makers and those who need plenty of I/O pins in a compact form factor.

The board's affordability is particularly noteworthy - at roughly $2 with no additional import fees expected, it represents an accessible entry point for electronics enthusiasts. This pricing strategy could make it especially appealing for educational settings, prototyping, or projects where multiple boards might be needed.
