Last summer Pi-oT introduced a Raspberry Pi add-on board of the same name targeting commercial & industrial IoT automation. The project was launched on Kickstarter and backers should have received their rewards.
The DIN-rail enclosure included with the RPi HAT was popular, so they decided to work on a Pi-OT MKR module enclosure with a similar form factor but instead of using screw terminals for ADC input and relays, they routed some of Raspberry Pi GPIO pins to the terminal, added a breadboard to the case for prototyping, as well as a fan for cooling.
Pi-oT MKR module key features:
- Compatible with any Raspberry Pi board with 40-pin GPIO header
- Screw terminals – 21 GPIO’s including the I2C pins, 5V, 3.3V and GND from Raspberry Pi header routed to screw terminals
- Integrated Breadboard
- Integrated Cooling – 5V header for included fan
- Circuit Protection
- Port protection – 330 Ohm resistor in series to protect each I/O from over-current.
- Integrated 5V input circuit protection
- Enclosure – DIN rail mount, screw hole mounting options
- HAT compatible – You can still connect any HAT on the 40 pin header
It is purely a hardware project and no extra software is needed. It can be useful for prototyping, people wanting a DIN rail case, and/or in projects where jumper cables may not be suitable, for example, due to vibrations that make lead the cables to slip out.
Pi-oT MKR module has just launched on Kickstarter with a symbolic $1 funding target. The early bird reward starts at $30 for one module with the enclosure. Shipping adds $8 to the United States and $18 to the rest of the world with delivery expected for March 2020.
