+## Using the NanoDAP USB debugging probe
+
+This is a mini-HOWTO on installing the appropriate firmware and adapter software, it is loosely based on [this tutorial by RAK](https://docs.rakwireless.com/Product-Categories/Accessories/RAKDAP1-Flash-and-Debug-Tool/Quickstart/#rak4600-evaluation-board).
+
+### Required hardware
+
+The [RAKDAP1/NanoDAP](https://store.rakwireless.com/products/daplink-tool) is a very reasonably priced ($10) USB-based debugging probe. It can be used on many ARM targets but is particularly suited for the nRF52 CPUs. It seems to be based on the ARM [daplink](https://daplink.io/) [project](https://github.com/ARMmbed/DAPLink). The fork of this project is located here: [nanoDAP](https://github.com/wuxx/nanoDAP). The fork is fairly old with respect to the latest daplink goodness, but it seems fine.
+
+If you are looking to buy a probe, there are many other daplink-based devices available. They are suspected to be mostly identical. If you find one that works well, please add a note to this document.
+
+### Required software
+
+You'll need to install the [pyocd](https://pyocd.io/) application to allow VSCode to talk to the NanoDAP. You first install the tool itself but then must add the support files for the nrf52840:
+
+```bash
+pip3 install pyocd
+pyocd pack --i nrf52840
+pyocd pack -s
+```
+
+If you are developing on a linux system, you will need to install the udev rules for the NanoDAP.
+
+This is done by copying the rules file from the pyocd distribution to the udev rules directory [per these instructions](https://github.com/pyocd/pyOCD/tree/main/udev).
+
+### Connecting the NanoDAP to your nRF52 target
+
+The NanoDAP has a 10-pin connector, but only three of these pins need to be connected:
+
+- **Ground**: Connects to the ground on the target.
+- **TMS-IO**: Connects to SWDIO on the target.
+- **TCK-CK**: Connects to SWCLK on the target.
+
+Some web instructions recommend connecting the RESET and 3V3 pins, but this is usually not necessary.
+
+#### Wiring Guide

+
+### Using the NanoDAP with VSCode
+
+The Meshtastic project has a special build environment/target which has been configured to work with the NanoDAP. To use it select the "env:rak3631_dap" target via the command palette or in the bottom left of your VSCode/PlatformIO window. Once that target is selected it changes two things:
+
+- Device programming is no longer performed via the USB bootloader. Instead you you select "Upload" it will use the NanoDAP to program the device.
+- The "Debug" button in VSCode will be enabled. If you click that button it will launch the ICE assisted debugger and you can set breakpoints etc...
