With just a regulator, the chip and three MOSFETs it allows remote control of an RGB colour effect by an Android or Apple phone. Part of the work is being done by the phone app called Happy Lighting, which has to arrange connection, note the location for specific unit control, and provide a human control interface. The controller does appear to remember the last colour setting after a short delay. Probably to avoid making too many writes to the memory. So you could theoretically connect, set and forget if you wanted a specific colour. I'm not a huge fan of loading random apps on my phone in case of malware issues. I'm also aware that there are always security issues in any communication network that could allow a bluetooth device like a keyboard to self-run devious strings of keypresses (rubber ducky). Especially given the capabilities of the processors used in many wifi and bluetooth products. The processor datasheet can be found by searching for xinchip xc610 There is a higher pin count version available, which explains the missing PWM1 module. From the datasheet there does seem to be a significant amount of memory on the chips. I wondered if it might just have been referring to an upper externally addressable range. I guess that's to support the use of more bloated library style code. The quiescent current of the chip with well written software that puts it into a proper sleep state is just 1uA - or 14uA in suspended mode. Pretty neat little controller. Very minimalist, and using the firmware to do the serious stuff.
