Omi Wearable Main Board and Charger Bill of Materials
Bill of Materials for the Omi2 wearable device featuring Nordic nRF5340 and nRF7002 for wireless connectivity, motion sensing, and dual MEMS microphones.
Overview
This bill of materials (BOM) provides a complete component list for the Omi2 hardware, including the main board, charger board, and mechanical assembly. The design utilizes the Nordic nRF5340 SoC and nRF7002 Wi-Fi companion chip for dual-radio connectivity. Key peripherals include the STMicroelectronics LSM6DS3TR-C 6-axis inertial module, TDK MMICT5838 MEMS microphones, and a Puya P25Q16SH 16Mbit flash memory. The power subsystem features Texas Instruments BQ25101 for battery charging and TPS628438 for power regulation, alongside various passives from Murata, Yageo, and SGMICRO.
Use Cases
