Add Tip Ask Question Comment Download Step 1: Preparation RPi Zero Both Raspberry Pi Zero and Raspberry Pi Zero W is ok.

WiFi version can make subsequent setup easier but in contrast it may draining more power continuously, i.e.

LCD HAT Waveshare released 2 LCD HAT for RPi Zero, both have a tiny square LCD.

This resolution is capable to emulate many retro game console in the CRT TV age, e.g.

NES at 256 x 240 resolution, we can cut 8 pixels from both left and right overscan area and make it become 240 x 240.

Pin Header To closely fit for the Waveshare 1.3 LCD HAT, it require a 8 mm tall 2 x 20 pins header.

But I cannot buy one with 8 mm tall, so I will modify from a 12 mm tall pin header.

LiPo Battery The interior size between RPi and LCD HAT can fit for a 5 mm x 23 mm x 45 mm battery, any LiPo battery with protection circuit that within this dimension should be ok.

Tiny LiPo Charge Board I have some 10 mm x 10 mm tiny 5 V LiPo charge board in hand.

It is small enough for this project, but the limitation is it only can charge the battery up to 50 mA current.

Wrist Strap Since this Game pad is so tiny and easy to slip from hand, it is recommended wearing a wrist strap while playing it.

According to the RPi Zero reduced schematics, there are only 2 pins direct connected to 5 V, it is USB plug and PAM2306 regulator.

All other parts powered by regulated 3.3 V and 1.8 V.

Assume we do not use any external USB device while powered by battery, the key factor is the regulator.

According to PAM2306 datasheet, there are still keep over 90 efficient for 3.3 V output when the input voltage dropped to 3.5 V.

RPi Zero average draw around 100 - 200 mA and the LiPo is around mAh, the discharge rate is around 0.5 C.

It can still utilise 90 of LiPo capacity before drop below 3.5 V.

Ref.: Note: According to my simply test, the battery can last over 90 minutes while WiFi turned on.

But we need a corresponding low profile male pin header at RPi Zero to make it.

The male pin header should be 8 mm tall, but I cannot find on the web.
