Amazing product. Suitable for light duty jobs as the flame is relatively small than the standard torches. Soldering iron works too. The heatgun works too, a little hard to get it started though, requires an external flame to ignite the sides. It also consumes alot of gas resulting in low usage time. Overall, it's a good product, suitable for very light duty jobs.

zzzackk thx so much for explaining the schematics to us!!

The electronics of the GY20451 The version of the GY20451 supplied to us contains only ten electronic parts. Thus, the scheme is quickly reconstructed and worked out in the illustration below. The 12 V supply voltage is converted into 5 Vdc in U1, an AMS1117, to power the microcontroller. Both the input and output of this stabilizer are decoupled with capacitors C5, C1 and C2. LED1 is connected to the 5 V output via the series resistor R1. An STC15W104 is used as microcontroller. It has a built-in clock generator, so no external parts are necessary in this scheme. Two square waves with a frequency of 40 kHz appear at the outputs P3.2 and P3.3. These two signals drive the two inputs of U3, a TCA4427. That is a double 'High-speed Power MOSFET Driver'. The outputs are connected by means of two MOSFETs either to ground or to the 12 V power supply. These two outputs directly feed the two piezoceramic resonators TX1 and TX2.

Works well! Took me a bit of time for me to get to know how to use it.
