RAK WisMesh 1W Booster Kit

nRF52840 + SX1262 1W

I checked the board label and image: this is RAK WisMesh 1W Booster KitINFO_UF2.TXT identifies the shared RAK4631 recovery family. Check the kit label: RAK WisBlock RAK4631 and RAK WisMesh 1W Booster Kit need different firmware for their radio hardware.

Prepare the board

The WisBlock Starter Kit and WisMesh 1W share the same bootloader identity. Match the selected firmware to the kit label before continuing.

1Connect a USB data cable and double-press RESET until the RAK4631 drive appears.
2Select INFO_UF2.TXT from that drive. It confirms the shared recovery family and S140 6.1.1, not which kit is connected.
3Copy the verified UF2 for your selected kit to RAK4631 and wait for the drive to disappear as the device reboots.

Detect firmware foundation

Select INFO_UF2.TXT from RAK4631. It is read entirely in this browser, never uploaded, and its contents are discarded after identity parsing.

Select INFO_UF2.TXT from the mounted bootloader drive to detect its SoftDevice foundation.

Review and verify

Waiting

1Confirm the exact board pictured above.
2Select INFO_UF2.TXT so the browser can resolve the exact SoftDevice foundation without uploading the file.
3Prepare the matching release artifact; its Minisign signature, UF2 structure, byte count, and SHA-256 are checked locally.
4Download the verified UF2, follow the board preparation instructions, and copy it to the bootloader drive.
5The bootloader drive disappears when the device reboots.

No full-chip erase. Every published byte is signature- and hash-verified before device access.

Confirm the exact board before preparing its verified UF2 download.
