| The second purpose is to use a chain of shift registers to provide chip select (CS) signals. It is functionally equivalent to a DOUT module, but the header is directly compatible with GPIO on the Core. | The second purpose is to use a chain of shift registers to provide chip select (CS) signals.

| - | 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. | + | All parts are THT, start with resistors and caps, IC sockets then headers. |
