+Dual core Arm Cortex M0 microcontroller designed to run MicroPython.
+There are four varieties of this board produced by RPi. The differences
+are whether they come pre-installed with header pins and a debug socket
+and if they have a WiFi adapter on board.
+===Tools===
+Read this [[https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf|guide]]. Within
+is the setup procedure for development tools is as follows:
+<code>
+wget https://raw.githubusercontent.com/raspberrypi/pico-setup/master/pico_setup.sh
+sh pico_setup.sh
+</code>
+This will install the ARM compiler, OpenOCD, the SDK, examples, and various other things.
+OpenOCD is built from source with the following options:
+<code>
+./configure --enable-ftdi --enable-sysfsgpio --enable-bcm2835gpio --enable-picoprobe
+</code>
+===J-Link===

+Segger J-Link can be use to interact with the PICO via the debug port.
