| - The parallel mode is a special feature, used for high-rated motors, requiring more than the 1.2A current limit. | |||
| - In this mode, the channel's directional pins and output pins are shorted; only one motor is connected to a motor driver i.e. two channels, giving a current capacity of 2.4A. Thus, one high rated motors can be controlled using ESP32. | |||
| - Note: The directional pin shorting is done by a manual DPDT switch. If the user turns on TB_A switch then the first motor driver goes into the parallel mode and its directional pins are shorted, where GPIO connections are IN1 = IN3 = 25 and IN2 = IN4 = 26. This is all done automatically. Also for parallel mode, the J1 and J2 junctions need to be shorted. | |||

Please remove the parallel mode section from Readme.

| - There is an inbuilt BAT760 diode on the USB line on ESP32. If different voltages are applied at Vusb and Vin, then the voltage with bigger magnitude will be given to LD1117 (LDO on ESP32); often the voltage will be the same on Vin and Vusb i.e 5V. | |||
| - But, the usage of the SS14 (currently, 1N5417 in previous edition) diode on the Vin path, which has more **Vf** (forward voltage) than the BAT760, will create a voltage indifference and in a simultaneous power supply condition, USB will be selected as its voltage will be more than Vin. | |||

@SuperChamp234 please review the changes here. Looks like everything's okey |
Why have you changed the naming scheme? Just call it SRA Board 2024.
