It also comes with an ESP8266 WiFi module, so you can connect to the...

The mbed is a tool for rapid prototyping with microcontrollers using the beefy LPC1768 ARM Cortex M3 chip. While it looks like a classic breadboard-friendly breakout board, this dev board has a few tricks up its sleeve. First of all, underneath the PCB is a second LPC chip which acts as the programmer: when plugging into a USB port the mbed shows up as a flash drive...

Discontinued - you can grab the Black Magic Probe with JTAG Cable and Serial Cable - V2.3 instead! If you've got a modern ARM chip devboard you'll notice that it has one of those tiny 2x5 connectors on it. Those are SWD ports, and they're used when you need to program or debug an ARM chip like those on the Particle boards. So, say you want to get into the weeds on...
