I have a few blank Xwhatsit Beamspring BLANK PCBs for sale. You have to order and solder the ICs, Resistors and Capacitors on your own.
Message me your offers, shipping is 2 or 3 euros worldwide (With regular post non tracked and uninsured, other shipping options also available for a higher cost) . If you want the solenoid driver as well, I am happy to price them at a discount for both together. I have to check on shipping as the weight will be slightly higher, but it should be around 2 to 3 euros.
If you need multiples, happy to discount them.
