At this point the question is no longer whether a new device runs DOOM, but rather how well. In the case of Anker’s Prime Charging Station it turns out that it’s actually not too terrible at controlling the game, as [Aaron Christophel] demonstrates. Unlike the similar Anker power bank product with BLE and a big display that we previously covered, this device has quite the capable hardware inside.
According to [Aaron], inside this charging station you’ll not only find an ESP32-C3 for Bluetooth Low Energy (BLE) duty, but also a 150 MHz Synwit SWM341RET7 (Chinese datasheet) ARM-based MCU along with 16 MB of external flash and 8 MB of external RAM. Both of these are directly mapped into the MCU’s memory space. The front display has a 200×480 pixel resolution.
This Synwit MCU is a bit of a curiosity, as it uses ARM China’s Star-MC1 architecture for which most of the information is in Chinese, though it’s clear that it implements the ARMv8-M profile. It can also be programmed the typical way, which is what [Aaron] did to get DOOM on it, with the clicky encoder on the side of the charging station being the sole control input.
As can be seen in the video it makes for a somewhat awkward playing experience, but far more usable than one might expect, even if running full-screen proved to be a bit too much for the hardware.
