Buy RF PACK S3 — $28.99 USD | Back to Wiki Home | PINGEQUA Support Page

Requirements

Item Notes
M5Stack StickS3 Required host device
RF PACK S3 board The expansion module
Bruce firmware v1.14+ Do NOT use v1.12 or v1.13
USB-C cable For flashing firmware
Computer For running the web flasher

Step 1 — Flash Bruce Firmware v1.14+

⚠️ Critical: You MUST flash Bruce v1.14 or later before attaching the RF board. Bruce v1.12 and v1.13 are missing the required SPI and power patches — they will produce a CC1101 NOT FOUND error.

  1. Open bruce.computer/flasher in Google Chrome or Microsoft Edge (Web Serial API required).
  2. Connect your M5Stack StickS3 via USB-C.
  3. Select the latest stable release (v1.14 or newer).
  4. Click Flash and follow the on-screen instructions.
  5. Wait for the flash to complete, then reboot the device.

For more details, see the Firmware Guide.

Step 2 — Attach the RF PACK S3

  1. Power off your M5Stack StickS3.
  2. Align the RF PACK S3 with the expansion header connector on the bottom of the StickS3.
  3. Press firmly until fully seated — no soldering required.
  4. Power on the device.

Step 3 — Configure CC1101 (Sub-GHz / 433MHz)

Once Bruce firmware is running with the RF board attached:

Menu → RF → CONFIG → RF MODULE → CC1101 (legacy)

After selecting CC1101, the module will be recognized and ready for use in the RF menu.

Step 4 — Activate nRF24L01 (2.4GHz)

No configuration is required for nRF24. Simply:

Activate the nRF24 module from the Bruce menu — it is operational immediately.

Verification

After setup, confirm the following:

  • Bruce firmware version is v1.14 or later (visible in Settings or boot screen)
  • No CC1101 NOT FOUND error on boot
  • CC1101 appears in Menu → RF
  • nRF24 activates without error
