14140^9

2 layer board of 2.75 x 2.60 inches (69.8 x 66.1 mm).
Shared on May 22nd, 2018 22:05

RPUno

ATmega328P based controller board with options for DIN mounts and 3.5mm connections. Eight digital I/O (10, 11, 12, 13, 14*, 15*, 16*, 17*) with level shift, the last four (*) are also analog channels (0..3). Four 22mA current source for use with loop sensors are also available with enables (5, 6, 3, 4). One 17mA current source for the pulse sensor with enable (7). ICP1 is pulled down when enough current (>7mA) arrives from the pulse sensor. Alternat power input may be enabled (9), and power to the shield VIN pin may be disabled (2). Power with 7 thru 36V DC.

17323^2

2 layer board of 2.90 x 2.90 inches (73.7 x 73.7 mm).
Shared on March 29th, 2018 19:25

RPUlux

Controller board with six AL8805 constant current drivers connected to PWM pins of an ATmega328p. Analog channels ADC0, ADC1, and ADC2. ADC0 and ADC1 also have an N-CH MOSFET that may be used to sink a few amps of current. Two 22mA current source for various task. ADC6 measures input voltage (7 thru 36V DC) and ADC7 measures input current. SHLD_VIN that can power a shield may be disabled with IO2 (so it can power off a Pi Zero on the RPUpi shield)

16197^3

2 layer board of 2.40 x 2.10 inches (61.0 x 53.4 mm).

RPUpi

Shield for RS422 over CAT5 with a Pi Zero host. It is a multidrop serial bus. I use it with RPUno or Irrigate7 with the AVR toolchain found on Raspbian, which means I can compile bare metal programs and then upload the firmware with the avrdude tool to a serial bootloader on one of the RPUno or Irrigate7 daisy-chained to the Pi Zero. The exposed network surface of Raspian on the Pi Zero is nil by default so it will need to be configured for some sort of remote access, I use SSH.
