The RAK WisBlock is a low power modular hardware system that can be used to build Meshtastic devices. Soldering is only required for the optional OLED screen.
RAK Wireless currently sell a [Meshtastic Starter kit](https://store.rakwireless.com/products/wisblock-meshtastic-starter-kit) that has the minimum you need to get started. If you wish to purchase parts separately, you will need a [base board](https://store.rakwireless.com/collections/wisblock-base), a [core 4631 LPWAN module](https://store.rakwireless.com/collections/wisblock-core/products/rak4631-lpwan-node), and optionally a GPS Sensor, screen or other module to build a Meshtastic device. Please ensure you choose the correct operating frequency for your country when purchasing.
Please see the RAK documentation for the correct way to connect your hardware to ensure that you do not damage the device. There is currently no pin required to pair RAK devices via BLE.

Flashing the firmware is a simple process. Connect your device to your computer via USB, click the reset button twice, and a drive will appear. On Windows, Linux, or Mac, drag the appropriate .uf2 firmware file onto the root of the drive and the device will restart and the firmware will be updated. Or, you can use [Meshtastic-flasher](https://github.com/meshtastic/Meshtastic-gui-installer). RAK have also provided [Installation instructions](https://docs.rakwireless.com/Product-Categories/WisBlock/RAK4631/Quickstart/#rak4631-lora-mesh-via-meshtastic) for Meshtastic.

The [RAK11200](https://store.rakwireless.com/products/wiscore-esp32-module-rak11200) is currently only supported on the RAK5005-O base board. This provides the benefits of WiFi, but sacrifices the very low power consumption of the nRF microprocessor used on the RAK4631.
- ESP32-WROVER microprocessor - Bluetooth 4.2 & WiFi 802.11 b/g/n
Further information on the RAK11200 can be found on the [RAK Documentation Center](https://docs.rakwireless.com/Product-Categories/WisBlock/RAK11200/Overview/#product-description).
The RAK11200 does not contain a LoRa transceiver, and this needs to be added separately in the form of the [RAK13300 LPWAN module](https://store.rakwireless.com/products/rak13300-wisblock-lpwan). This occupies the IO Port of the base board.
Further information on the RAK13300 can be found on the [RAK Documentation Center](https://docs.rakwireless.com/Product-Categories/WisBlock/RAK13300/Overview/#product-description).
Further information on the RAK1921 can be found on the [RAK Documentation Center](https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1921/Overview/#product-description).
Similar modules are widely available from other suppliers, but do check the boards as some have the VDD and GND pins swapped round.

To add a GPS to the RAK5005-O base board, you need the [RAK1910 GPS sensor](https://store.rakwireless.com/collections/wisblock-sensor/products/rak1910-max-7q-gnss-location-sensor). It is supported on slot A of the 5005 board via UART.
Further information on the RAK1910 can be found on the [RAK Documentation Center](https://docs.rakwireless.com/Product-Categories/WisBlock/RAK1910/Overview/#product-description).
To add a GPS to the RAK19003 base board, you need the [RAK12500 GPS sensor](https://store.rakwireless.com/products/wisblock-gnss-location-module-rak12500). It is supported via I<sup>2</sup>C on slot B for firmware versions 1.49 and above.

The [RAK13002 IO Module](https://store.rakwireless.com/collections/wisblock-interface/products/adapter-module-rak13002) can be used to, amongst other things, add a user button to the RAK base boards (excluding the RAK19003 Mini base board). It features a number of different interface options:
There is development activity in progress to get sensors such as this added to the Meshtastic Core.

## MAC Address Conflict
Some of the RAK Meshtastic starter kits that come pre-installed with Meshtastic have an error where the same MAC address is applied to more than one unit. If you have a number of RAK devices but are unable to connect to more than one of them, or they will not talk to each other despite being on the same mesh, please try a [factory reset](/docs/settings/misc#factory_reset) using the Meshtastic CLI, and then restart the device. This reset will wipe all settings on the device back to their defaults including the stored MAC address. If you have already configured your node and wish to keep the configuration, then please export it first:
- `meshtastic --export-config > settings_file.txt` - This will save the node's settings to the file `settings_file.txt`
- `meshtastic --set factory_reset true` - This will reset the device and wipe the configuration
- Power cycle the device
- `meshtastic --configure settings_files.txt` - This will restore the settings saved in the file `settings_file.txt`
