Loli dual-channel one-way brushed ESC-with additional power supply

Kaiyuan Square did not find any Loli dual-channel one-way brush ESCs, so I simply made my own and drew this one according to the schematic diagram of the Loli master. There are two AO3402s per channel, one 3402 is nominally 4.02A, and the two total 8A. The maximum current of a 1020 coreless cup is within 5A. If the nominal current of the mos tube is not too weak, it is enough to drive the 1020 coreless cup. Considering that there may be different requirements for 1S or 2S, 1S requires a boost module and 2S requires a buck module, so the board does not come with BEC, and you need to configure the BEC according to your needs. The BEC part painted on the board uses the 1S boost module (5V3A) by default (purchasing link: https://item.taobao.com/item.htm?id=626746867442). Of course, you can also choose 2S or 3S according to your own motor. Then you can choose a buck module for the battery. You can even cut off the BEC part of the current board and put the BEC module on the back of the board, so that the overall size can be reduced by nearly half. Someone has already tested this board and verified that there is no problem, so you can use it with confidence.
