Internal USB UART Console Mod

In a very hacker‑friendly move, the manufacturer provided test points for the USB D⁺/D⁻ data lines of the charging port on the PCB. This allows you to add internal USB hardware that can be connected to a PC by plugging a normal USB‑A‑to‑C cable into the charging port (which will still charge the R36S at the same time). The test points are on the “bottom” side of the PCB; you have to remove the board from the case to access them.

I used this to add a USB‑UART adapter that gives convenient access to the serial console (this will, for some people/situations, be more convenient than plugging in a USB keyboard or using Wi‑Fi + SSH).

I opted for a tiny USB‑UART module from AliExpress because it’s neater, but you can also remove the USB connector of any other one. Beware that the UART side must use 3.3 V signals (not 5 V). This pulls the 3.3 V power supply from the UART test points on the R36S (note that I set the jumper on the module to 3 V input), which has the downside that the USB device only registers on the host when the R36S is powered up. If I were to do this again, I would find a point to grab the 5 V supply from the charging port instead.

Heatsink Mods

The R36S handheld can get pretty toasty during marathon gaming sessions, but a few clever cooling tricks can keep it chill. Whether you add some copper sheets, thermal pads, and extra vent holes for passive heat‑spreading or an active cooling fan, these low‑cost mods make a big difference—and your games stay smooth without the sweat.
