Inspired by Megazoid's https://oshwlab.com/mzoid/ardubrofx-mini-cornetto-trilogy">Ardubro FX Mini and my Casio/Sony/National MSX mood board, I designed this Arduboy FX clone with a big 2.42" SSD1309 OLED so that I, with my middle-aged eyes, can actually enjoy its library of miniscule masterpieces. It uses the standard wiring so it's easy to load up the 128Mbit flash with selections from the <a target="_blank" rel="noopener nofollow ugc" class="editor-link relative pointer-events-auto a cursor-pointer
underline " href="https://www.bloggingadeadhorse.com/cart/Cart.html?list=Curated.csv">online cart builder - you just have to apply the SSD1309 patch on upload.
A BOM file listing all the necessary components as well as recommended sources is included in PDF format. Components should be wired up per Megazoid's "ProMicro Regular" schematic with one exception. As the built-in regulator of the cheap Arduino Pro Micro clone I used couldn't handle the larger OLED, I added a TPS61023-based module to supply 5V to all components. The slide switch used to power on the unit is wired to EN and GND on the regulator board. Additionally, 470uF capacitor was added to the 5V rail to stabilize it.
Hoping to simplify some of the wiring, I decided to solder the Arduino Pro Micro, Flash Memory and 5V boost boards to a single mini PCB using standard pin headers. To make room for everything, I shifted the Pro Micro a couple of positions off of the PCB and did not solder the unused RX, TX, RAW and GND pins nearest the USB-C connector (see photos). The positioning of the screw posts for the main PCB assume that you'll do the same!
With a 3000mAh (11.1 Wh) LiPo installed you'll enjoy many hours of gameplay. Smaller capacity batteries will work fine, though the cavity in the back case is designed to accommodate 904360 and 103665 form factors.
Please be aware that this design uses hand-soldered boards and will take even experienced hobbyists a few hours to assemble!
