TheColonelYoung/RingOne
3D air mouse based on STM32 - Can be used for controlling CADs and every other manipulation in 3D space. Is based around STM32L452, IMU LSM6DSL (gyroscope and accelerometer) and Bluetooth low power module RN4871.

The UT6MA2TCR is a MOSFET made by ROHM Semiconductor in a HUML2020-L8 package with 6 pins. 1 N-Channel + 1 P-Channel 180pF、305pF 2.5V 2W 30V 4.3nC@10V、6.7nC@10V 46mΩ@10V、70mΩ@10V 4A N-Channel + P-Channel HUML2020-L8 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:UT6MA2TCR, from EasyEDA) and its footprint (EasyEDA_Cloud:U-DFN2020-6B_L2.0-W2.0-P0.65-BL, from EasyEDA), ready for a KiCad board. 1,990 are in stock at JLCPCB (part C3278150). 2 open-source boards in 2 repositories on GitHub use it.
