IMU-G-1020-S is an industrial 6-axis IMU module from Shenzhen SZLIGHT (SZLCTEK), built on a purple PCB (V1.0, 2025-08-29) around a HiPNUC HI14-series MEMS inertial chip (silkscreen HIPNUCHI14). The HI14 family offers gyro ranges of ±2000 to ±4000 °/s and accelerometer ranges of ±24 to ±32 g, outputs fused Euler angles and quaternions at up to 1000 Hz over UART/USB, and applies full-temperature compensation from -40 to +85 °C for harsh outdoor environments. This board breaks out 5V/GND, TXD/RXD, an RSYNC sync pin and RS-485 (485A/485B) through an 8-pin connector, targeting robot attitude sensing and stabilization. No public page exists for the module vendor, so core specs follow the official HiPNUC HI14 datasheet.
