# TMF8801 Time-of-Flight SensorBoard ## Description TMF8801-1BM time-of-flight (ToF) sensor from ams-OSRAM. It comprises electronic components such as resistors, capacitors, voltage regulators, and GPIO connectors. The logic signals are managed via Mosfets BSS138 while the Sensor IC is powered & controlled by a 3.3V AP2112K Voltage Regulator. ## Project Details - **Owner:** michaelcox - **Created:** 12/23/2024 - **Last Updated:** 4/7/2025 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ ## Key Components ### IC1 — [TMF8801-1BM](https://www.flux.ai/vasyl/tmf8801-1bm~2z4.md) - Manufacturer Name: ams-OSRAM USA INC. - Part Type: Distance Measuring - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Part Number: TMF8801-1BM - Datasheet URL: https://ams.com/documents/20143/4409395/TMF8801_DS000648_9-00.pdf **Pins:** - EN [pin 9] - GND [pin 8] - GNDC [pin 2] - GNDV [pin 11] - GPIO0 [pin 3] - GPIO1 [pin 10] - INT [pin 4] - SCL [pin 5] - SDA [pin 6] - VDD [pin 7] - VDDC [pin 1] - VDDV [pin 12] ### J1 — [QWIIC I2C JST Connector](https://www.flux.ai/vasy_skral/qwiic-i2c-jst-connector~d55.md) - Datasheet URL: https://media.digikey.com/pdf/Data%20Sheets/JST%20PDFs/SR%20Connector.pdf - Manufacturer Name: JST Sales America Inc. - Manufacturer Part Number: SM04B-SRSS-TB - Part Type: Connector **Pins:** - 1 [pin 1] - 2 [pin 2] - 3 [pin 3] - 4 [pin 4] ### J3 — [Pin Header 01x08 2.54mm Vertical](https://www.flux.ai/vasyl/pin-header-01x08-254mm-vertical~95x.md) - Part Type: Connector **Pins:** - 1 [pin 1] - 2 [pin 2] - 3 [pin 3] - 4 [pin 4] - 5 [pin 5] - 6 [pin 6] - 7 [pin 7] - 8 [pin 8] ### Q1 — [BSS138](https://www.flux.ai/vasy_skral/bss138~3ld.md) - Manufacturer Name: onsemi - Part Type: Transistor - Datasheet URL: https://www.onsemi.com/pdf/datasheet/bss138-d.pdf - Manufacturer Part Number: BSS138 **Pins:** - D [pin 3] - G [pin 1] - S [pin 2] ### Q2 — [BSS138](https://www.flux.ai/vasy_skral/bss138~3ld.md) - Part Type: Transistor - Datasheet URL: https://www.onsemi.com/pdf/datasheet/bss138-d.pdf - Manufacturer Part Number: BSS138 - Manufacturer Name: onsemi **Pins:** - D [pin 3] - G [pin 1] - S [pin 2] ### U1 — [AP2112K-3.3TRG1](https://www.flux.ai/adrian95/ap2112k-33trg1~zlq.md) - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Part Number: AP2112K-3.3TRG1 - Manufacturer Name: https://www.diodes.com/assets/Datasheets/AP2112.pdf - Part Type: Integrated Circuit - Datasheet URL: Diodes Incorporated **Pins:** - EN [pin 3] - GND [pin 2] - NC [pin 4] - VIN [pin 1] - VOUT [pin 5] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/michaelcox/tmf8801-time-of-flight-sensorboard~dj](https://www.flux.ai/michaelcox/tmf8801-time-of-flight-sensorboard~dj).* --- *Generated from [https://www.flux.ai/michaelcox/tmf8801-time-of-flight-sensorboard~dj](https://www.flux.ai/michaelcox/tmf8801-time-of-flight-sensorboard~dj)*
