Full Description
RockBase NM-CYD-C5 – ESP32-C5 Official 2.8" Touch Display Development Board
The RockBase NM-CYD-C5 is a powerful all-in-one ESP32 development board built around the ESP32-C5-WROOM-1-N16R8 module. It combines a 2.8-inch 320×240 color TFT touchscreen, 16MB Flash, 8MB PSRAM, and the latest dual-band Wi-Fi 6 technology into a compact platform for modern embedded applications.
Unlike traditional ESP32 display boards, the NM-CYD-C5 supports 2.4GHz and 5GHz Wi-Fi 6, Bluetooth LE 5.3, Zigbee 3.0, and Thread, making it an excellent platform for Matter-compatible smart home devices, industrial IoT, dashboards, control panels, HMI projects, and wireless gateways.
The board maintains compatibility with the classic Cheap Yellow Display (CYD) form factor while adding significantly more memory, faster wireless connectivity, and modern IoT protocols. It also features dual USB-C ports, MicroSD card support, onboard RGB LED, and expansion connectors for additional peripherals.
