Hi All,
I'm creating a project with Raspberry PI B+ where I will get energy from a truck (12~27v) or/and a solar power (6v 5.6w) to charge a battery and keep the device running until the battery finishes or the power supply is off; moreover, I will read 5 sensors DS18S20 using 1wire and convert it to i2C as the raspberry doesn't work well with a lot of sensors DS18S20.
I bought some products from adafruit and Abelectronics.co.uk and those devices worked perfect, but now I need to transform it in a hat and put over the raspberry pi using the rasp's header.
I will attached a USB 3G modem and USB GPS to send data though the internet. I've checked and it should use between 0.4A (idle) ~0.8A (transmiting)
The circuit that I built plus the excel document with all part numbers that I decided to buy can be found on this link http://goo.gl/RKlcqQ. Please could you help me to check if the circuit is ok? I'm not good at circuits but I did a lot of research and I ended up with this schematic. enter image description here
The battery that I will use has 6600mAh.
I accept suggestions and please if you need a project like this feel free to use/change this project, also I can provide the code to control the GPS/3G and sensors, just send me an email if you need it.
Products that I used as example
