rpi interfaces

5 different boards to allow for 1-Wire,I2C and various other inputs for raspberry pi3. Relay outputs, both conventional and solid state. Boards were produced and delivered promptly. Very competitive price and 2 day delivery, total 5 calendar days, including a weekend. The quality looks professional and even the smalles texts are easily readable. No problems nor questions arose during the entire process. The online progress report was a nice touch. Sample pic of one of the boards uploaded.
