Ss relay
About the Ss relay PCB
Ss relay is an open source PCB design by BadenLab, published on GitHub under the MIT license. It is a 2-layer board measuring 98 × 78 mm, with 31 components from 13 distinct parts.
Other key parts include the AQY221R2S. By type, the board carries 12 ICs, 9 connectors and 2 resistors.
It belongs with the test & measurement designs in this gallery.
From the project
An arbitrary-spectrum spatial visual stimulator for vision research
This board controls the LED power lines from the Lightcrafter by opening and closing them using solid state relays. The relays are controlled by a 5V signal (in this case the inverted blanking signal).
