ESP32-C5 dual-band WiFi 6 SoC enters mass production, ESP32-C5-DevKitC-1 board launched for $15

ESP32-C5 development board

Espressif Systems has just started mass production of the ESP32-C5 RISC-V wireless microcontroller with dual-band (2.4/5 GHz) WiFi 6, Bluetooth LE, and 802.15.4 (Zigbee, Thread) connectivity. The ESP32-C5-DevKitC-1 development is now available for about $15 on AliExpress, and should soon show up on the company’s Amazon store. So far, WiFi-capable Espressif microcontrollers have only supported 2.4 GHz WiFi since it’s cheaper and offers better range for IoT applications, but some applications may benefit from 5 GHz WiFi, so the company unveiled the ESP32-C5 dual-band WiFi 6 and BLE RISC-V MCU in June 2022. Design probably took longer than expected, but we noted documentation for an ESP32-C5 beta board in March 2024, and finally, the company has just announced that mass production has started. We’ll have a closer look at the ESP32-C5-DevKitC-1 board in this article, since it is different from the beta board. ESP32-C5-DevKitC-1 specifications: Wireless module –  ESP32-C5-WROOM-1 SoC […]

10-cent WCH CH570/CH572 RISC-V MCU features 2.4GHz wireless, Bluetooth LE 5.0, USB 2.0

CH572 development board

Patrick Yang, CTO at WCH, has recently unveiled the CH570 RISC-V SoC with 2.4GHz wireless and USB 2.0 (host & device) as an upgrade to the popular CH32V003 general-purpose RISC-V MCU with more features at the same low price (10 cents). CH570 also comes with 12KB SRAM and 256KB flash (vs 2KB SRAM and 16KB flash for the CH32V003), offers up to twelve GPIO,  six PWM, I2C, UART, SPI, and a 20-channel key detection module. There’s also the CH572 with the same features, except it also supports Bluetooth LE 5.0. As a side note, I wrote about the CH572 RISC-V MCU with BLE in 2019, but I guess it was scrapped likely because it had OTP instead of flash…, and the new CH572 (2025) is different.
