esp32 makes an open source handheld game console [Copy link]

 

 

Recently I found an interesting thing called odroid-go, which is an open source handheld game console that can play games like Super Mario and supports Arduino, micropython and other functions. With io expansion, it is a portable game console. It can even be used as a razor.

I can't resist the temptation of this kind of thing, but the size is a bit large, and it's not easy to buy, so I decided to make it myself. After
a simple plan, it should take about a week.
The first day of overall design

1, the
original appearance is relatively large, I hope to reduce it to the size of a credit card, which can be easily carried out.

2. The circuit board
adopts the mode of core board + expansion board separation. This makes it convenient to replace other main controls in the future.
The core module is an ESP32 Wrover module + CP2102 serial port
expansion board with buttons, power amplifier speakers, SD card slots, and battery charge and discharge management circuits.

I finished the circuit and layout two days ago, and sent it out for board making today. See the circuit diagram in the attachment. Wait two days.

I remember there was an electronic product on the Internet that looked very similar to this called Palm Treasure. Is this the 300-in-1 product?

A bit like

Credit card? That's too small.

I like the buttons to be distributed on the left and right.

Never heard of it.

I thought about that layout and realized it was difficult to make smaller, so I gave up.

Fortunately, it should be possible to make it smaller.
