Jymc220bi Schematic 2021 [upd]

Provides smooth starts/stops and supports voltage control input for speed regulation. Wiring and Connection Guide

Look for charred components near the large MOSFETs/SCRs, as these are the most common failure points due to motor overload. jymc220bi schematic 2021

In earlier versions, the input was direct analog. The often includes a BT Module (e.g., JL AC692X) that outputs analog audio and I2S. The schematic should show a jumper or resistor option to select between analog and digital input modes. jymc220bi schematic 2021

The 2021 version has a silkscreen marking "2021-06-15" near the mounting hole. Older versions (2019) have linear regulators and no ferrite bead. jymc220bi schematic 2021
