Step 2: Hardware Installation

a. Insert RF Board: Insert the RF Board into the SD Slot of the Cardputer.
b. Connect Grove Cable: Connect the RF Board GPIO pins to the Cardputer using the Grove cable.

Step 3: Select RF Module via Physical Switch

For CC1101 (433 MHz):
1. Toggle the physical switch to 433 MHz
2. Menu: RF → CONFIG → RF MODULE → CC1101 (Legacy)

For NRF24 (2.4 GHz):
1. Toggle the physical switch to 2.4 GHz
2. You can now use NRF24 functions

Note & Alert (Bruce Firmware):

DO NOT USE v1.13 STABLE: Due to SPI bus timing changes in the Bruce 1.13 stable release, it may cause a "CC1101 Not Found" error on M5StickC Plus 1.1 hardware.

USE LATEST BETA: Please flash the Latest Beta Version from the official Bruce web flasher. The Beta version includes critical patches for SPI initialization and power management (AXP2101) that ensure 100% module recognition.

Due to low-power hardware design, anti-interference of 2.4 GHz devices, and legal limits, the NRF24 Jammer range is naturally limited.
