# Bluetooth Power Logger ## Description A Bluetooth Power Logger utilizing Seeed Studio's XIAO nRF52840 uC Power Monitoring handled using the INA260 IC, this design should be safe for usage under 36V 8A. Higher current rating will require larger trace widths on the main power trace. Attach your Power Supply to V+ and GND. Then attach your loading device to LOAD+ and GND. ## Project Details - **Owner:** jlamflux - **Created:** 11/8/2023 - **Last Updated:** 11/21/2023 - **Visibility:** Public ## Key Components ### INA260 — [INA260AIPW](https://www.flux.ai/jlamflux/ina260aipw~d4.md) - Manufacturer Part Number: INA260AIPW - Datasheet URL: https://www.ti.com/lit/ds/symlink/ina260.pdf?ts=1699435968584&ref_url=https%253A%252F%252Fwww.google.com%252F - Manufacturer Name: Texas Instruments **Pins:** - A0 [pin 5] - A1 [pin 4] - ALERT [pin 7] - GND_1 [pin 6] - GND_2 [pin 11] - IN-_1 [pin 14] - IN-_2 [pin 15] - IN-_3 [pin 16] - IN+_1 [pin 1] - IN+_2 [pin 2] - IN+_3 [pin 3] - NC [pin 13] - SCL [pin 9] - SDA [pin 8] - VBUS [pin 12] - VS [pin 10] ### J1 — [DB126V-5.0-3P-GN](https://www.flux.ai/jharwinbarrozo/db126v-5p0-3p-gn~6j.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector - Manufacturer Part Number: DB126V-5.0-3P-GN - Manufacturer Name: DIBO - Datasheet URL: https://datasheet.lcsc.com/lcsc/1912111437_DIBO-DB126V-5-0-3P-GN_C395850.pdf **Pins:** - PIN1 [pin 1] - PIN2 [pin 2] - PIN3 [pin 3] ### J2 — [Pin Socket 01x06 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x06-254mm-vertical~yiu.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **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] ### U1 — [Seeed Studio XIAO nRF52840](https://www.flux.ai/seeedstudio/seeed-studio-xiao-nrf52840~fc.md) - Manufacturer Part Number: 102010448 - Part Type: Microcontroller - Manufacturer Name: Seeed Studio - Datasheet URL: https://files.seeedstudio.com/wiki/XIAO-BLE/nRF52840_PS_v1.5.pdf - Purchase Url: https://www.seeedstudio.com/Seeed-XIAO-BLE-nRF52840-p-5201.html **Pins:** - 3V3 [pin 12] - 5V [pin 14] - D10_MOSI_P1.15 [pin 11] - D7_RX_P1.12 [pin 8] - D8_SCK_P1.13 [pin 9] - D9_MISO_P1.14 [pin 10] - GND [pin 13] - P0.02_A0_D0 [pin 1] - P0.03_A1_D1 [pin 2] - P0.04_SDA_A4_D4 [pin 5] - P0.05_SCL_A5_D5 [pin 6] - P0.28_A2_D2 [pin 3] - P0.29_A3_D3 [pin 4] - P1.11_TX_D6 [pin 7] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/jlamflux/bluetooth-power-logger~y3](https://www.flux.ai/jlamflux/bluetooth-power-logger~y3).* --- *Generated from [https://www.flux.ai/jlamflux/bluetooth-power-logger~y3](https://www.flux.ai/jlamflux/bluetooth-power-logger~y3)*
