1.5 week ago I have designed and ordered R2 PCBS of the AEMSUCA. With 0.8x0.6inch it's smaller than R1 (1x0.8inch). In a few days when the PCBs arrive I will assemble and test one. I want to sell these on Tindie in 5 weeks. I have just requested quotation from Elecrow for assembly of qty50. If the board works fine I will place the order asap.
