This is a Infrared ESP8285 Wireless WIFI Transceiver Module.The ESP-01M module with ESP8285 as the core be used as the master control, The program is the same as ESP8266. The module board is equipped with an infrared receiving tube and an infrared transmitting tube which are respectively io14 and io4 controlled, and a burning port is set apart. The demonstration program can read and emit infrared key values and raw codes,user can record infrared remote controls in your home , which can be controlled remotely if connected to the Internet of things platform.
Firmware Update:
1.Connect IO0 and GND pins.
2.Connect module to PC by USB to UART converter.
3.Open software 'FLASH DOWNLOAD TOOLS V3.6.4'.
4.Set parameters.
5.Click START to download firmware.
6.Remove connect between IO0 and GND pins then update complete.
Connect with TTL downloader:
GND -------- GND
5V -------- 5V
RX --------- TX
TX --------- RX
When programming a program, IO0 and GND must be short-circuited, and the module needs to be powered on again; after programming, disconnect IO0 and GND and power on again to run the program normally.
Note:
When supplying power, you need pay attention on 5V and GND. There is no reverse connection protection for the circuit, otherwise the chip may be burned out if connected incorrectly.
Package included:
2* ESP8285 ESP-01M Digital Infrared Transceiver Sensor Module

As mentioned in an earlier review, you must flash program this board at 5V and run it in operation mode at 5V as well.Here is part of my ESPHome YAML with the HW configuration that worked best for me using the latest HomeAssistant and ESPHome compiler software:esphome:name: ir-blasterfriendly_name: IR Blasteresp8266:board: esp01_1m# Enable logginglogger:remote_receiver:pin:number: GPIO14inverted: Truemode: INPUT_PULLUPdump: allremote_transmitter:pin: GPIO4# Infrared remotes use a 50% carrier signalcarrier_duty_percent: 50%

This device was pretty easy to integrate into Home Assistant, and has been stable so far. Note that you can set this device up as a IR receiver and an IR transmitter. So, for example, you could receive IR codes in one room on one of these devices, and then use Home Assistant to repeat in a different room on a different one of these devices.However, if you do not have a USB to TTL cable, you will need to order one to use this device. There's no direct connect USB port onboard (which is party of why this is such an attractively priced option).That said, I have such a cable, and flashing was a breeze. I like that out of the bag the jumper was in place to permit flashing the device. I found that it was happiest being flashed when VCC was set to 3.3v. After flashing, you have to remove the jumper to boot, and the device insists on having 5v to boot, even though flashing was fine at 3.3v.When configuring for Home Assistant, here are the most important YAML settings, which I had to piece together from several google searches:esp8266:board: esp8285remote_receiver:pin:number: GPIO14inverted: Truemode: INPUT_PULLUPdump: raw(I found dump: raw to be most useful for working with non-standard remotes, check the other options defined in the HA module "Remote Transmitter" if you want to take advantage of some of HA's more intelligent options).remote_transmitter:pin: GPIO4# Infrared remotes use a 50% carrier signalcarrier_duty_percent: 50%Hope the above saves you some time in getting up and running with this high-quality and easy to use device!Further thoughts, a few days later: While I've flashed enough ESP8266 boards for it to not faze me, it'd be a nice upgrade of this product to provide a USB port. Almost everything has a USB C or at least USB micro port these days, so much so that on the rare occasions I have to flash the "hard way" that means I have to go dig out the USB to TTL cable out of storage. Adding USB would also make it simpler for less experienced users to get up and running.

I flashed Tasmota onto one of these and used it to learn remote IR codes of all my household devices. I use m5 atom lite units around the house to blast IR to the air conditioners and other devices with the codes learned. Cheap and effective

I wish that these were shipped such that they were a little more protected, like in a small box. They arrived in anti-static bags, within a soft mailer. So, a couple of the header pins were ever so slightly bent. Not a biggie and they were bent back into position by hand easily enough.Interfacing with the chip with 3v serial and a 5v power supply is easy enough. There are plenty of options for programming ESP8266 modules (ESP8285 is what's *actually* on this board, but libraries accommodate). I started off with some simple test code via Arduino IDE, and everything was working fine. Played with updating the code via OTA. Really a flexible platform. After looking around some, I am testing out ESP Easy at this time. I am able to capture and emit IR codes for my TV, etc over the network just fine. I'll probably try out ESPHome on the second module.This is a small package that is easy to work with if you do your research. Ideally it would have more documentation from HiLetgo and have some additional protections in place for newcomers. (Like reverse polarity protection on the 5v rail.) That said, I believe that this module could meet a bunch of people's needs. People probably aren't aware or aren't wanting to deal with a solution that is so "raw" to work with out of the box. That "rawness" leaves room for much flexibility though! Very pleased. I'll definitely be getting any updated version (ESP32 & beyond) that they release down the road.
