Two months ago, I published post about Small Relay Box II. There was full design of small DCTR-driven Relay box. A week ago, I assembled the first piece of PCB and I discovered two bugs (one HW – wrong NC a NO contact description on silkscreen layer and one SW – wrong relay pin mapping).

Small Relay Box II
Two weeks ago, I published post about Small Relay Box. I made new and more useful version with NC and NO contacts…
Small Relay Box
Some of my posts were dedicated to Remote controlled relay board or [2]. But in many situations, this board was too big. I made another board for this cases and, of course, I made new application for DCTR module. Now, straight, for DPA, but if you want, you can make a simple P2P application from published source code.
IQRF Relay Board II – upgrade to DPA
One of my first post on this site was IQRF Relay Board. I made a simple board with shift register and eight relays. All was controlled by IQRF P2P application. Now it is time to make some upgrade, upgrade to DPA and make real IQMESH device. How is it simple? You will see inside…
Wireless ADC to Relay Example
Sometimes, you need to measure analog signal and then switch something on or off according to the result. This short example shows, how to do it. Everything you need is DDC-SE-01 module as a sensor module and DDC-RE-01 as relay module. Of course you need DK-EVAL-04 or CK-USB-04 for both of them as a master module.
