LILYGO T-Dongle-C5: Strengths & Caveats
✔ Advantages
- Equipped with Espressif ESP32-C5HR8 delivering dual-band 2.4 GHz/5 GHz Wi-Fi 6, BLE 5.0, and 802.15.4 (Thread/Zigbee)
- Space-saving physical design integrating a microSD card slot directly inside the USB Type-A male connector
- Built-in STEMMA QT / Qwiic interface for plug-and-play modular sensor prototyping
- Optional 0.96-inch 160x80 color IPS display provides onboard visual telemetry
✖ Documented Caveats
- Switching to external IPEX antenna connectors requires desoldering and rotating onboard surface-mount resistors
RockBase IoT NM-CYD-C5-Colorful External Antenna ESP32-C5 Development Board: 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
