thingiverse

The FriendlyElec [NanoPi M4](https://www.friendlyelec.com/index.php?route=product/product&product_id=234) is a RK3399 SoC based ARM board. It has the same form of factor as the RPi B3+ and has ports and interfaces compatible with RPi B3+ too. I mounted it inside my main PC's to avoid having an external case using one of the free PCI slots. ## Shopping list - a Nanopi M4 (v1) [Arcade kit](https://shop.pimoroni.com/products/arcade-parts-kit?variant=29420556419155) - a momentary button of ~6mm diameter. Something like [this](https://www.kjell.com/se/produkter/el-verktyg/elektronik/elektromekanik/strombrytare-for-elektronik/tryckstrombrytare/strombrytare-1-pol-frantill-rod-p36011). It can be installed and connected to IO pins for e.g. power-cycle. - 4x M2.5 screws It will take up to 2 PCI slots to fit the board and the [dedicated heatsink](https://www.friendlyelec.com/index.php?route=product/product&product_id=235&search=m4&description=true&category_id=0&sub_category=true). There's also place for the Bluetooth and Wi-Fi antennas that come with it, and for an additional RTC battery. An angled usb-c connector can be used to power it up, or even the 5V pins on the IO.
