Czech hobbyist electronics agency Prokyber has launched a brand new, sub-$5 breadboard-friendly growth board for these trying to mess around with the RISC-V structure: the Ch32-Ant.
“It was created, as a result of I wanted an affordable growth board with a STEMMA QT connector,” the board’s designer explains. “The [WCH Electronics] CH32V003 appeared like the right MCU [Microcontroller Unit] for the duty. It is Arduino-compatible, helps USB (pure software program USB), and is cost-effective.”

The Ch32-Ant is a compact design constructed with breadboard use in thoughts, although that includes a STEMMA QT connector for solderless enlargement — discovered on the brief aspect of the board, reverse a USB Sort-C connector for knowledge and energy. It is constructed round WCH Electronics’ CH32V003F4U6, an ultra-low-cost 32-bit RISC-V microcontroller working at as much as 48MHz and with 2kB of static RAM and 16kB of on-chip flash. It is also switchable between 3.3V or 5V logic ranges, for many who want it.
This is not Prokyber’s first shot at a low-cost RISC-V growth board: again in October final 12 months the corporate unveiled the ESP32-C6-Bug, based mostly round Espressif’s ESP32-C6FH4 microcontroller. For individuals who picked one up, there’s excellent news: the Ch32-Ant is pin-compatible with the sooner ESP32-C6-Bug, making it a drop-in cost-reduced alternative for many who can get away with decrease efficiency and who do not want wi-fi radios.
The Ch32-Ant is offered to order now on Prokyber’s Tindie retailer at $4.99; a schematic is linked from the shop web page.
