DIN6DOUT4 module

A combination of DIN and DOUT on the same PCB


Please refer to the uCapps pages for DIN and DOUT.

Notice that DOUT 1 and 2 are connected through UDN2981 source driver chips. When a voltage (e.g. 12V) is supplied to J13, the DOUTs will be shunted to this voltage; no inversion is needed. Resistors R1-16 provide current limiting.

If normal DOUT behaviour is desired for DOUT 1/2, simply bridge a resistor from the resistor pad closest to J11/J12 directly across to pins 1-8 of the unmounted IC11/12

v1.0: first release.


The 1206 caps and SMT parts should be soldered first. Note the orientation of ICs! In general they will have pin 1/16 nearest the decoupling cap. Pin 1 for RNs is marked with a circle, important as these chips are also polarised. Some headers are marked as “socket this side.” To use the module normally, install the headers on the rear side.

Note the instructions for DOUT1/2. You either need ICs 11/12 and resistors vertically mounted or spanning the outermost pads in place of IC11/12.

Interconnection to Core

J89 connects to J89. J89A is for cascading further modules.


The PCB is 100*100mm with 3.6mm diameter holes centred 3.5mm from the edges.
