# STC3115 Module ## Description This project is a Battery Management System (BMS) built around STMicroelectronics' STC3115AIQT battery monitor IC. It uses I2C for communication, features alarm management, and supports battery charging. The power supply, battery connection points, and debug interface are facilitated through connectors. #project #Template #charger #monitor #reusable #module #batterycharger #template #bms #STC3115 #stm ## Project Details - **Owner:** leoo22 - **Created:** 5/26/2024 - **Last Updated:** 10/30/2025 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **Copies:** 2 ## Key Components ### J1 — [Pin Socket 01x08 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x08-254mm-vertical~cz1.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] - Pin_7 [pin 7] - Pin_8 [pin 8] ### J2 — [Pin Socket 01x02 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x02-254mm-vertical~k8w.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] ### J3 — [Pin Socket 01x04 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x04-254mm-vertical~kks.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] ### Q1 — [NPN Transistor](https://www.flux.ai/jharwinbarrozo/npn-transistor~hqd.md) - Leakage Current: 1e-13A - Beta / hFe: 100 - Package or Case Code: SOT-223 **Pins:** - B [pin 2] - C [pin 3] - E [pin 1] ### Q2 — [NPN Transistor](https://www.flux.ai/jharwinbarrozo/npn-transistor~hqd.md) - Leakage Current: 1e-13A - Package or Case Code: SOT-223 - Beta / hFe: 100 **Pins:** - B [pin 2] - C [pin 3] - E [pin 1] ### SW1 — [Push Button](https://www.flux.ai/jharwinbarrozo/push-button~eqk.md) - Part Type: Switch - Manufacturer Part Number: B3FS-1050P - Datasheet URL: https://datasheet.lcsc.com/lcsc/1809271215_Omron-Electronics-B3FS-1050P_C231326.pdf - Manufacturer Name: OMRON **Pins:** - P1 [pin 1] - P2 [pin 3] ### SW2 — [Push Button](https://www.flux.ai/jharwinbarrozo/push-button~eqk.md) - Manufacturer Name: OMRON - Datasheet URL: https://datasheet.lcsc.com/lcsc/1809271215_Omron-Electronics-B3FS-1050P_C231326.pdf - Manufacturer Part Number: B3FS-1050P - Part Type: Switch **Pins:** - P1 [pin 1] - P2 [pin 3] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/leoo22/stc3115-module~qc](https://www.flux.ai/leoo22/stc3115-module~qc).* --- *Generated from [https://www.flux.ai/leoo22/stc3115-module~qc](https://www.flux.ai/leoo22/stc3115-module~qc)*
