simply power up the Pi with the SD card in, and nothing else connected, and look for the flickering activity light on the Pi. if your struggling to see that, or you have a black case, then you can test the Pi in its own. If your TinyPi has a white back, you should be able to just see the Pi activity light flickering through the plastic. if its the wrong image, or it didnt write to the SD Card correctly then you will struggle. The first thing to check if you are having issues, is the sd card and its image. So those are the basics, but what issues might you see? Is my SD Card image written OK? This makes the connection with no soldering at all, lowering the skill level needed to build, and making it ideal for kids and school clubs The pins have a static end which is designed to insert into the gpio hole of the pi, and a springy end designed to contact with the TinyPi board. We bought many different styles of pins to try and find the best solution, however we ended up getting some custom pins made.

We decided with the Pro version that we wanted it to be as easy to build as possible, which led us down the pogo pin path. The original TinyPi needed ninja soldering skills to be able to build. The TinyPi service also talks to the power system of the TinyPi board, reading the battery voltage and power button state in order to show a battery gauge and menu system. The buttons on the TinyPi board are directly linked to the gpio pins, and they are monitored by a TinyPi service, which converts the button presses into gamepad events. Once there has been i2c communication, the TinyPi board then sets a timer, and after 5-6 seconds of no communication, it is assumed that the Pi is no longer there, and the power gets cut. The conversation between the Pi and the TinyPi board is used as a ‘keepalive’ signal, so the TinyPi board knows the pi is there and to keep the power active. This communication happens over i2c, needing just 2 pins to do all the work. This chip runs the power system, and helps us to get the battery voltage and the power button status over to the Pi. The TinyPi board has an atmega328 chip on board, the same as in early Arduino boards.

Feel free to skip over this if your just after a quick fix. To understand some of the issues, we have to first understand some of the inner workings.

Most of these are pretty easy to fix, so have no fear!! The secrets of TinyPi So as more kits are hitting the real world, there are a few niggles that might catch you out.
