NEVER TRY TO FLASH WHILE YOUR DEVICE IS CONNECTED TO MAINS POWER!!! In some cases you will need to solder wires directly on the chip's pins which requires some experience and good soldering equipment.ĭO NOT CONNECT DEVICES TO MAINS AC POWER WHILE THE COVER IS OPEN AND CIRCUIT BOARD IS EXPOSED!!! In most cases those pins are available on the PCB in the form of pin holes or solder pads but pin headers or jumper wires need to be soldered or otherwise applied. This is done by connecting our serial-to-USB converter TX and RX pins to the ESP RX and TX pins and powering the chip with the 3.3V and GND pins.

We need to connect to the serial programming interface of the ESP chip. Read our article on MQTT to learn why it is essential in Tasmota. To use it to its fullest potential you need an MQTT broker. Tasmota is designed to be controlled and communicate via MQTT.

IFLASH DUAL USB CODE

If you want to modify the code or default settings and compile your own Tasmota firmware. Esptool.py - the official flashing tool from Espressif for ESP82XX and ESP32.ESP-Flasher - GUI flasher for Tasmota based on esptool.py for ESP82XX and ESP32.

IFLASH DUAL USB SOFTWARE

Needed Software ~ Tasmota Firmware Binary ~ĭownload a Tasmota firmware binary file (.bin). This is usually done by connecting to a Tasmota Wi-Fi Access Point with your smartphone (or tablet or computer with Wi-Fi). Tasmota installed from a precompiled binary needs to be configured to work with your Wi-Fi network before you can access the Tasmota web UI. You need a computer with a USB port to upload the firmware to your device and configure it.

Choose according to your jumper wire connectors. Pin headers come in male or female version.

You could use any kind of wire but jumper wires (also called DuPont wires) are more practical than soldering and desoldering. At worst, you could get away with holding the headers tightly with jumper wires in pin holes during flashing but it is not a foolproof process and flashing might fail. If you're intimidated by soldering there are 3D printed jigs available for different modules and devices. If you're new to soldering check out some soldering tutorial videos while you're at it. To solder you'll of course need a soldering iron, soldering tin and some flux.

A PC power supply can be a source for 3.3V DC power. When using an external 3.3V supply, simply ensure the ground (GND) of both are connected, this ensures a common ground. The ESP requires at least 150mA, many 3.3V serial programmers do not supply this much current as many serial programming tasks do not require a large amount of power. Many CH340G devices will not work, the "golden CH340G" has a voltage regulator on it to supply enough power to the ESP device - many do not. Some devices, such as NodeMCU, D1 mini or M5Stack products, have a USB upload port and the serial-to-USB adapter built in. You MUST make sure the data (RX and TX) and VCC pins are set for 3.3V.

Some adapters can be switched between 3.3V and 5V for the data pins, but still provide 5V on the power pin which will irreparably destroy your device.
