My first v2 boards

A project log for 4014 LED minimodule

A cheap, small module that displays two 7-segments digits with simple multiplexing

The DirtyPCBs package is here and the boards are just as expected.

The experience gained with the previous runs has been useful, look at my page describing the tiny differences between DirtyPCBs and DangerousPrototypes: Dangerous Prototypes vs DirtyPCB : same maker, different process

In this case : no via, so no tented via problem, the milling has not been modified (much better for soldering the LEDs while still attached), the serial number marking is manually located in a blank place (thanks !)

The only defect is the one found yesterday by @al1 (see a second prototype - and some bugs (by al1))and it's just a matter of reversing F1.

Note: this board is good only for LEDs WITH an internal reverse diode.

Time to solder a few now...

Between the v1 and v2 boards, I must have enough digits to prototype a first #Discrete YASEP ;-) Which will I choose ? v2 is great because there is less wiring (easier routing) and no series resistor but the matching LEDs I have are cold white, and warm white goes to v1 boards...

If you are interested to get some of these boards, send me a message !
