Bare board for the RF231 module
Some testing of the RF231 modules. The balun on one module didn't get seated properly and range was poor, but they did work.
A gutted non-functional Ethernet switch that made a quite nice base/power supply for a couple breadboards. On the breadboards: my Xmega breakout, RF231 wireless module, FTDI USB-serial, and various other components just plugged into the breadboard.
801.15.4 wireless module using the AT86RF231. Board design done in Eagle, PCB made by Seeed, assembled with a hot air gun.
An AVR Xmega32 breakout board of my own design. Board design done in Eagle, PCB made by Seeed, assembled with a cheap hot air gun.
A breakout board for the LPC1343, a Cortex M3 ARM microcontroller with USB support. Designed in Eagle, PCB made via Seeed, first board assembled using hotplate technique.
Character LCD is hooked up to SPI via a 74595 shift register.
Stellaris Launchpad, a cheap Cortex M4 dev board, stacked on a protoboard with a couple I2C devices (an ADC and FRAM).
