⚡ WeAct Logic Analyzer V2: $10 USB 3.0 Board

WeAct Studio has released the Logic Analyzer V2, a low-cost board based on the WCH CH32H417 microcontroller. Priced at $10, this compact device functions as a 16-channel logic analyzer with a bandwidth of up to 200 MHz. It connects via a USB 3.0 Type-C port and is compatible with Sigrok and Pulseview software forks.

The board features a dual-core architecture with QingKe RISC-V5F cores running up to 400 MHz and QingKe RISC-V3F cores up to 144 MHz. It includes a Graphics Processing Hardware Accelerator, 896KB of SRAM, and 960KB of flash memory. A dedicated 304 KB slot is reserved for user applications or custom firmware at address 0x0809E000.

WeAct states that the board supports three distinct operational modes: logic analyzer, USB-serial combined with DAP, or custom user firmware. These modes are stored at different addresses in the flash memory. Users can switch between these applications by simply pressing the physical button located on the board.

Connectivity is provided through a 20-pin GPIO header, which exposes 16 GPIO pins and 4 ground pins. The single USB 3.0 Type-C port handles power delivery, data transfer, and programming tasks. This design allows for flexible usage scenarios while maintaining a small form factor and minimal cost.
