ARPIS

thingiverse

A.R.P.I.S. (Another Raspberry Pi Stack)I designed this stack, because i wanted a flexible stack case for several rpi2 and or rpi4 boards. Furthermore i also wanted to add a small UPS to the stack to keep the raspberry running when the power comes off.I used the Type-C 15W 3a 18650 Lithium Battery charger Module with backup power:https://nl.aliexpress.com/item/1005005040201132.html?gatewayAdapt=glo2nldFor the voltmeter i used this one:https://nl.aliexpress.com/item/32817684162.htmlFor the battery meter:https://nl.aliexpress.com/item/32851338868.htmlThe pogopins i used:https://nl.aliexpress.com/item/4001085839296.htmlAnd for the contact islands:https://nl.aliexpress.com/item/4000528572282.htmlRaspberries are powered by the pogo pins and the 40-pin connector.All the units are powered also with the pogopins.An external powersupply 5V 3A (1A/rpi) is also needed to keep the batteries charged and the raspberries powered.If extra cooling is needed, a cooling fan 30x10 can be placed inside.
