There are 2 revisions of this generation motor: | |||
*One is the G30D version with 3 capacitors and the debug points hidden on the back of the PCB | |||
*The other is the standard single capacitor version common in most G30 models | |||
[[File:NinebotMaxGen1ESC.jpg|thumb|center|400px|A Gen 1 ESC has bullet connectors and a silver metallic housing. Newer units may have writing as shown in this image.]] | |||
The G30D gen 1 also has 2 different board layouts, marked '''AA01''' and '''AB02''' on the back. | |||
[[File:NinebotMaxGen1G30DESC.jpg|thumb|center|400px|The G30D ESC has 3 capacitors on board rather than the usual 1 on the regular G30 ESC.]] | |||

The second generation of the ESC was more similar to that of the newer generation Xiaomi Mi3 and Mi4 scooters. | |||
It has a black plastic housing and features screw terminals less prone to melting. | |||
It was based on an AT32 chip and incompatible with STM32-based Custom Firmware and STLinking. | |||
This model can only be flashed with some types of firmware, and can only be STLinked with [[ScooterHacking ReFlasher]]. | |||
