Ok, this is kinda cool. In case you wanted to read the actual specs: https://www.hmd.com/en_in/hmd-touch-4g/specs?sku=1GE001CPG30... and https://en.wikipedia.org/wiki/HMD_Touch_4G RTOS Touch on a Unisoc T127... that's cool. Amazed they can get the price that low.
CPU: single A7, 1GHz
RAM: 64MB LP-DDR2
Flash: 128MB NAND
I think the OS is an update of the Mocor RTOS by the SoC vendor Unisoc.
I am curious if there are 3rd party apps on this device. If nothing else, it would be a fun challenge to write apps for something constrained like this.
