It seems like hacker-friendly ARM development boards are just exploding into the market right now. Here’s one we haven’t looked at yet. The SolderCore is made by Rowley Associates and is packed with features which help to explain the $80 price tag. [CharlieX] just ordered one and posted a bit about his first day with the device.
First off, it’s obviously the Arduino form factor. We think that’s a nice touch in a development board, but we still wish the Arduino folks hadn’t offset that one header way back when. That chip at the center packs quite a wallop; an 80 MHz ARM Cortex-M3 (from TI) with 512 kb of Flash memory and 96 kb of RAM. The in-built Ethernet jack is hard to miss, but right below it in this picture you can also see the USB On-the-Go connector. There’s a microSD card slot and both 3V and 5V regulators. [CharlieX] does a little hacking on the networking features offered, then takes a look at firmware upgrading. For that you’ll need an SD card formatted to FAT 16.
