RockBase IoT NM-CYD-C5-Colorful External Antenna ESP32-C5 Development Board Review: Dual-Band Wi-Fi 6 Touchscreen Node: Strengths & Caveats
✔ Advantages
- Dual-band Wi-Fi 6 (2.4 GHz and 5 GHz) accompanied by Bluetooth 5.3, Zigbee 3.0, and Thread 1.3
- Generous memory configuration featuring 16 MB flash memory and 8 MB PSRAM
- External IPEX 1 dual-band antenna delivering up to 3.7 dBi peak gain for enhanced wireless reach
- Dual USB Type-C ports providing separated native USB programming and dedicated CH340 UART console access
✖ Documented Caveats
- Primary SPI bus is shared across the display, touch digitizer, and microSD slot, requiring careful chip-select arbitration
- Hardwired pull-up resistors on IO8 and IO9 can cause bus impedance conflicts with external I2C peripherals
Radxa Rock 5B+ 12GB Review: Pocket Powerhouse Demands Active Cooling: Strengths & Caveats
✔ Advantages
- Dense high-speed storage expansion via dual M.2 M-Key slots operating at PCIe 3.0 x2
- Full-size HDMI input supporting 4K video ingestion alongside dual 8K HDMI outputs
- Integrated 2.5GbE Ethernet and onboard Wi-Fi 6/Bluetooth 5.2 connectivity
- Soldered onboard eMMC 5.1 storage eliminating socket-retention failure modes
✖ Documented Caveats
- Demands active cooling under sustained multicore or NPU load to prevent thermal throttling
- Full NPU and video acceleration features remain dependent on Rockchip vendor BSP kernels
- Requires a compliant USB-PD power supply capable of 30W or greater to ensure boot stability with peripherals
