# BLE Gas leakage detector Reference Design ## Description This project is a Bluetooth Low Energy (BLE) gas leakage detection system. It uses a BME680 sensor from Bosch Sensortec for gas detection and a BMD-330-A-R module from U-blox for BLE communication. It also features a user interaction button, RGB signaling LED, and is powered by two non-rechargeable AA batteries. #BLE #MCU #ReferenceDesign #project #referenceDesign #simple-embedded #ublox #template #reference-design ## Project Details - **Owner:** midu6725 - **Created:** 3/17/2024 - **Last Updated:** 3/17/2024 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **Copies:** 7 ## Key Components ### BAT1 — [BC2AAPC](https://www.flux.ai/vasy_skral/bc2aapc~866.md) - Datasheet URL: https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/1086/BC2AAPC.pdf - Manufacturer Part Number: BC2AAPC - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Name: MPD (Memory Protection Devices) **Pins:** - - [pin 2] - + [pin 1] ### IC1 — [BME680](https://www.flux.ai/vasyl/bme680~s5p.md) - Manufacturer Part Number: BME680 - Datasheet URL: https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bme680-ds001.pdf - Part Type: Specialized Sensors - Manufacturer Name: Bosch Sensortec **Pins:** - CSB [pin 2] - GND [pin 1] - GND [pin 7] - SCK [pin 4] - SDI [pin 3] - SDO [pin 5] - VDD [pin 8] - VDDIO [pin 6] ### IC2 — [TPS613221ADBVR](https://www.flux.ai/vasyl/tps613221adbvr~58b.md) - Manufacturer Part Number: TPS613221ADBVR - Part Type: Integrated Circuit - Datasheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=http%253A%252F%252Fwww.ti.com%252Flit%252Fgpn%252Ftps61322 - Manufacturer Name: Texas Instruments **Pins:** - GND [pin 2] - NC [pin 3] - NC [pin 5] - SW [pin 1] - VOUT [pin 4] ### LED1 — [LTST-C19HE1WT](https://www.flux.ai/vasy_skral/ltst-c19he1wt~x5i.md) - Part Type: LED - Datasheet URL: https://datasheet.lcsc.com/lcsc/2010222107_Everlight-Elec-19-237-R6GHBHC-A04-2T_C883183.pdf - Manufacturer Name: Everlight Elec - Manufacturer Part Number: 19-237/R6GHBHC-A04/2T **Pins:** - A - B - G - R ### PROG — [Connector 01x04 0.100](https://www.flux.ai/vasy_skral/connector-01x04-0100~go.md) - Part Type: Connector **Pins:** - 1 [pin 1] - 2 [pin 2] - 3 [pin 3] - 4 [pin 4] ### RST — [PTS815](https://www.flux.ai/vasy_skral/pts815~6b.md) - Datasheet URL: https://www.ckswitches.com/media/2728/pts815.pdf - Part Type: Switch - Manufacturer Part Number: PTS815 SJM 250 SMTR LFS - Manufacturer Name: C&K **Pins:** - ~1 [pin 1] - ~2 [pin 2] - ~3 [pin 3] - ~4 [pin 4] ### U1 — [BMD-330-A-R](https://www.flux.ai/vasy_skral/bmd-330-a-r~2dh.md) - Manufacturer Name: U-blox - Manufacturer Part Number: BMD-330-A-R - Datasheet URL: https://content.u-blox.com/sites/default/files/BMD-330_DataSheet_UBX-19033352.pdf - Part Type: Module - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - <= GND [pin 47] - GND [pin 3] - GND [pin 29] - GND [pin 1] - GND [pin 46] - GND [pin 16] - GND [pin 18] - GND [pin 5] - GND [pin 2] - GND [pin 45] - GND [pin 4] - GND [pin 30] - P0.00/XTAL1 [pin 13] - P0.01/XTAL2 [pin 14] - P0.02/AIN0 [pin 15] - P0.03/AIN1 [pin 19] - P0.04/AIN2 [pin 20] - P0.05/AIN3 [pin 21] - P0.06 [pin 22] - P0.07 [pin 23] - P0.08 [pin 24] - P0.09/NFC1 [pin 25] - P0.10/NFC2 [pin 26] - P0.11 [pin 27] - P0.12 [pin 28] - P0.13 [pin 31] - P0.14 [pin 32] - P0.15 [pin 33] - P0.16 [pin 34] - P0.17 [pin 35] - P0.18 [pin 36] - P0.19 [pin 37] - P0.20/TRACECLK [pin 38] - P0.21/~RESET [pin 39] - P0.22 [pin 40] - P0.23 [pin 41] - P0.24 [pin 42] - P0.25 [pin 6] - P0.26 [pin 7] - P0.27 [pin 8] - P0.28 [pin 9] - P0.29 [pin 10] - P0.30 [pin 11] - P0.31 [pin 12] - SWCLK [pin 43] - SWDIO [pin 44] - VCC [pin 17] ### USER — [PTS815](https://www.flux.ai/vasy_skral/pts815~6b.md) - Manufacturer Name: C&K - Manufacturer Part Number: PTS815 SJM 250 SMTR LFS - Part Type: Switch - Datasheet URL: https://www.ckswitches.com/media/2728/pts815.pdf **Pins:** - ~1 [pin 1] - ~2 [pin 2] - ~3 [pin 3] - ~4 [pin 4] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/midu6725/ble-gas-leakage-detector-reference-design~ej](https://www.flux.ai/midu6725/ble-gas-leakage-detector-reference-design~ej).* --- *Generated from [https://www.flux.ai/midu6725/ble-gas-leakage-detector-reference-design~ej](https://www.flux.ai/midu6725/ble-gas-leakage-detector-reference-design~ej)*
