По цене модуль соответствует ценам на чипы RTL8711AM.

Нету их.

WFM-400 (RTL8711AM)
WFM-410 (RTL8711AF)
WFM-250 (RTL8195AM)
WFM-250 is a single chip wireless Internet-of-Things module.
The advance Realtek RTL8195AM chipset combines an ARM-Cortex M3 MCU, WLAN MAC, a 1T1R capable WLAN baseband and RF.
It provides useful high speed connectivity interfaces, such as USB 2.0 host, USB 2.0 device, SDMMC HS, SDIO device, and MII/RMII interfaces.

Теперь цена на RAK473 такая 704,42 руб - уже дешевле ESP-32S и тем более WROM-32, но памяти в 5 раз больше (2.5 мегабайта).

RAK475 (RTL8711AM) 708,89 руб

Interesting. Thank you.

I wonder why they put it on UART0.

EMW3081 / taobao $3.95 RTL8711AM
EMW3082A - на 8711AF - прошивки подойдут к RTL00.
Внутренности под крышкой модулей (что удалось надыбать):

Производитель: EMW3081
В MXCHIP SDK присутствует базовый SDK от Realtek для RTL8195/871x чипов.

На схеме к SoC RTL8195/871x (уже который раз) отображен BT4.1/BLE + FM. Походу надо рыть в чипе - возможно он там есть...

(надо копнуть на предмет сертификации на FCC BT у кого на RTL871x...)
Встроенный UART бутлоадер (исходники, SDK, прочий софт, документация,... - всё уже есть):

----------
Интересные чипы:

MOC100 160MHz Cortex-M3 MCU + 512KB RAM + 2MB DRAM +WiFi (HT40) + 2MB SPI Flash

MOC200 160MHz Cortex-M3 MCU + 512KB RAM + 2MB DRAM +WiFi (HT40) + BT(BLE) + 2MB SPI Flash

= Полная смерть ESP-32S !

Нашел полную прошивку от EWM3081, с boot - 1,26 МБ (1 331 544 байт).

Это та прошивка (test.bin) что в прошивочном архиве или что-то другое?
P.S. Весьма приятное впечатление производит обширный набор SDK.

1) Да. 2) Да. Но только в плане подключения внешнего MCU ARM STM32... по SDIO к любому дешевому WiFi модулю. У модулей c RTL871xAx нет внешнего MCU. Есть зачатки нормального boot для RTL.
У них так-же есть файл управления spic для flash, не хватающий для сборки \sdk-ameba-rtl8710af-v3.5a_without_NDA_GCC_V1.0.0\component\soc\realtek\8195a\misc\iar_utility\common\flashloader\EWARM_bcut\FlashLoader.eww

Ешё в каком-то состоянии boot-пинов работает это:

Достаточно быстро записывает по YMODEM на 921600.

Разнообразные модули с RTL871x и RTL8195.
