Update time!
First batch have all sold and a second batch of PCB's are in production
The design has been changed slightly to stiffen up the units when assembled, the port pack and keypad are now one PCB with the LCD screwed into the centre of it, this also has the added advantage of getting rid of the LCD cable which will simplify assembly a little
Additionally DIP footprints have been added for the EEPROM's for storing test results which give us more assembly options if we can find a EEPROM that works here. These will also have a backplate with them (essentially another blank PCB) to protect the bottom of the logicboard from shorting on the unit you are working on and also providing a space a lithium flat cell could be installed in if you don't want the 18650 on the keypad board
Also I have had some interest in kit versions of these, if anyone else is interested in this please let me know.
The kit version will be a little cheaper than the assembled units but please don't expect them to be half price or anything like that as a very large proportion of the cost of these is the parts and not assembly time (I expect kit for to be somewhere around £200 vs £250 for the assembled units however the exact price will depend on the exact BOM cost once I have everything ordered)
