Batches of PCBs from Ivo of Knutsel.org:
The first batch was a new run of the LivingColors Arduino shield.
The second batch was a breakout board for the NiceRF SX1276 LoRa module. Here I experimented a little with contour routing.
The third batch was an adapter board to use no-name CC2500 modules in boards designed for the Quasar QFM-TRX1-24G. The boards are small (about 20 mm x 25 mm) and the minimal size for dirtypcbs PCB’s is 100 mm x 100 mm. Here I experimented with breakout panels, putting 4 PCB’s in one design.
