C64 Keyboard to USB Adapter based on the design by Mikkel Holm Olsen (https://symlink.dk/projects/c64key/).
Feature rich and very small ESP32-WROOM-32 adapter similar to one sold on eBay. More info about the project can be found in the link below.
- micro-USB port for power
- 3v3 regulator, can be connected with the "solder blob" type connector (XC6210)
- buttons for manual programming
- 1.27mm and 2.56mm pitch programming connectors (for ESP-Prog or similar)
- indicator LED...
Dallas Semiconductor OneWire extension cord terminal via RS422 interface. Is enable extens distance beetwen the microcontroller and OneWire devices up to 500 meters. Do not need programming. Required the exteraml impendance matching network applicable to used cable.
Order the design to me.
This is an adapter board that lets you use a Sanyo DB-L40 battery in a Tiger Telematics Gizmondo game console. This project is derived from the excellent design by [Re.Enthused](https://re-enthused.com/hardware/making-replacement-batteries-for-the-gizmondo/) with the change being that I wanted to use standard header pins instead of making springs. As a result, you'll find three holes to solder the...
same board as rev_3, with new layout and smaler PCB
- LDO changed to AP7361C-33ER SOT-223 (1117-3.3 compatible pinout)
- ESP-01/12 changed to ESP-Goofy (look for TheGoofy 2019 Adapter)
- small improvements
- silkscreen fixed
original designed in EAGLE
- board and schematic attached
PCB will be tested next days, before going in production
