Just simple pcb designed for custom application with Raspberry Pi
"Raspberry pi Custom Shield" that I have shared is a pcb with custom pin gpio selection to screw block connection, two relays drived to GPIO20 and GPIO 21, an RTC to give correct data to Raspberry.
Schematic and PCB file of "USB expander" show one my solutionon to expand USB and add two serial door connection to raspberry PI.
two DS18B20 sensors to D5
Also two sensors with DO directly to D6 and D7.
Spare headers for 3V3 and GND
All pins connected to header for use.
Designed to be used with Double Socket Dual Base Shield for WeMos D1 Mini
To test the series of sensors contained in the package "37 in 1 Sensor Module Board Set" which is sold by many sites it is possible to use this shield compatible with Arduino UNO original R3 and related clones.
On the board are available many connectors that are already properly connected with the digital or analog ports of Arduino.
In fact, the card, in addition to the sensors in the "37 in 1 Sen...
This is a Raspberry Pi Shield. 12V DC to input. The board will power the Pi through the GPIO using a switch power supply based around the ACT4065A IC. The input 12V comes in through the DC "IN" barrel Jack. Then is turned on and off through the TIP120 NPN Transistor which is controlled through GPIO 4 on the Pi and outputs the barrel Jack labeled "OUT". There is also another TIP120 NPN transistor c...
If you have a Wemos D1 mini card and you want to test the series of sensors contained in the package "37 in 1 Sensor Module Board Set" which is sold by many sites you can use this shield.
On the shield are available many connectors that are already properly connected with the digital or analog ports of the Wemos D1 mini card. On the board there is also already a power supply stage that allows powe...
