Flashing TYWE2L and TYLC5 with ESPHome or Tasmota: Is It Possible?

Question

Hi all, New to home automation and flashing esphome on a couple of different devices. One is a TYWE2L and the other a TYLC5. Is it possible to flash with esphome or tasmota?

Both those modules are build on ESP8285, so they are easily flashable with Tasmota and so on. You will need to provide power (3.3V), connect UART and GPIO0.

Here is more information on your modules:
TYWE2L is a low power-consumption built-in Wi-Fi module developed by Hangzhou. It consists of a highly integrated RF chip (ESP8285) and several peripherals, with a built-in Wi-Fi network protocol stack and rich library function

Pin number	Symbol	I/O type	Function
1	14	I/O	GPIO_14, correspond to MTMS of the IC (Pin 9)
2	12	I/O	GPIO_12, correspond to MTDI of the IC (Pin 10)
3	13	I/O	GPIO_13, correspond to MTCK of the IC (Pin 12)
4	5	I/O	GPIO_05, correspond to GPIO 5 of the IC (Pin 24)
5	4	I/O	GPIO_04, correspond to GPIO 4 of the IC (Pin 16)
6	GND	P	Power supply reference ground
7	3V3	P	Power supply pin (3.3 V)

Test pins:

Pin number	Symbol	I/O type	Function
-	IO2	I/O	UART1_TXD (interface for displaying module information)
-	RST	I/O	Reset pin
-	IO0	I/O	IO0 is involved in module startup. If IO0 is disconnected, the module enters the normal running state.

TYLC5 is a low-power embedded Wi-Fi module developed by Hangzhou Tuya Information Technology Co., Ltd. It consists of a highly integrated wireless radio frequency chip, ESP8285, and a few peripheral devices. It also has a built-in Wi-Fi network protocol stack and abundant library functions.

Pin No.	Symbol	IO Type	Function
1	ANT	-	RF antenna port, spot to solder external antennas
2	GND	P	Power reference point
3	GPIO12	I/O	GPIO_12
4	GPIO14	I/O	GPIO_14
5	GPIO4	I/O	GPIO_04
6	VCC	P	Power pin of the module (3.3V)

Test pins:

Pin No.	Symbol	IO Type	Function
-	TP1	Rst	Hardware reset pin; Cannot clear the distribution network information of Wi-Fi.
-	TP 2	I/O	GPIO0;Testing the module production.
-	TP3	U0TXD	User serial port; Information output from the serial port can be used for testing the module production.
-	TP4	U0RXD	User serial port; Information output from the serial port can be used for testing the module production.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
