This dual-mode development board is specially designed for the StickC Plus, integrating both A01-S2G4A00S2A (2.4GHz NRF24) and A07-S433A10S2A (433MHz CC1101) modules. Fully compatible with firmware, it features a plug-and-play design and supports both short-range and long-range wireless communication, making it ideal for IoT, wireless control, and development projects. Dual-module design: Supports both NRF24 (2.4GHz) and CC1101 (433MHz) communication. Tailored for StickC Plus, plug-and-play. firmware compatible, no complex setup required. High-performance communication for reliable data transmission. Physical switch for easy module selection 2.4GHz NRF24 Module (A01-S2G4A00S2A): Stable, high-speed short-range wireless communication. 433MHz CC1101 Module (A07-S433A10S2A): Low-power, long-range transmission Reliable performance with optimized signal layout and power design Usage Instructions 1. Flash Firmware (First-Time Setup). To use this board with StickC Plus, first flash the firmware. Follow the instructions to select the correct device (StickC Plus v1.1/v2) and complete the flashing process 2. Hardware Connection, Connect the board to the StickC Plus using the Grove cable or GPIO jumper wires. The GPIO pinout is pre-configured and compatible with firmware 3. Switching Between Modules, This board includes a physical switch to toggle between the two modules: To use the CC1101 (433MHz) module: 1. Toggle the switch to the 433MHz (CC1101) position 2. Navigate in the firmware: CONFIG MODULE 3. Select: CC1101 (legacy) To use the NRF24 (2.4GHz) module: 1. Toggle the switch to the 2.4GHz (NRF24) position 2. Navigate in the firmware: NRF24 CONFIG Pins 3. Select: NRF24 (legacy) 4.
