They put a STM8S003 inside the module and break STM8 GPIOs out. Only ESP8266 GPIO0 is accessible. The WiFi part runs AI flavor of AT firmware.
Wonder how they came to that decision?

Mainstream Value line 8-bit MCU with 8 Kbytes Flash, 16 MHz CPU, integrated EEPROM
active Active
The STM8S003F3/K3 value line 8-bit microcontrollers offer 8 Kbyte Flash program memory, plus integrated true data EEPROM. They are referred to as low-density devices in the STM8S microcontroller family reference manual (RM0016).
TheSTM8S003F3/K3 value line devices provide the following benefits: performance, robustness and reduced system cost.
Device performance and robustness are ensured by true data EEPROM supporting up to 100000 write/erase cycles, advanced core and peripherals made in a state-of-the-art technology at 16 MHz clock frequency, robust I/Os, independent watchdogs with separate clock source, and a clock security system.
The system cost is reduced thanks to a high system integration level with internal clock oscillators, watchdog, and brown-out reset.
Full documentation is offered as well as a wide choice of development tools.
