# Raspberry Pi 4 Hat Template ## Description Template for Raspberry Pi 4 Shield. Include an official pinout so you will always know Raspberry Pi names, the alternative roles of pins, which one is SDA, or SCL, etc. On PCB you can find the 3D model of the Raspberry Pi itself along with the board outline on the silkscreen. #RaspberryPi #Raspberry #Pi #RPi #Shield #template #project #project-template #raspberry ## Project Details - **Owner:** klong4 - **Created:** 2/20/2024 - **Last Updated:** 2/20/2024 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **Forks:** 5 ## Key Components ### D1 — [1N5819HW-7-F](https://www.flux.ai/jecstronic/1n5819hw-7-f.md) - Manufacturer Name: Diodes Incorporated - Manufacturer Part Number: 1N5819HW-7-F - Part Type: Diode - License: https://creativecommons.org/licenses/by/4.0/ - Datasheet URL: https://www.diodes.com/assets/Datasheets/ds30217.pdf **Pins:** - A [pin 2] - K [pin 1] ### H1 — [M2106-2545-AL](https://www.flux.ai/vasy_skral/m2106-2545-al.md) - Part Type: Standoff - Manufacturer Part Number: M2106-2545-AL - Datasheet URL: http://dpk3n3gg92jwt.cloudfront.net/domains/raf/pdf/RAF%20Catalog.pdf - Exclude from BOM: false - Manufacturer Name: RAF Electronic Hardware **Pins:** - P1 [pin 1] ### H2 — [M2106-2545-AL](https://www.flux.ai/vasy_skral/m2106-2545-al.md) - Part Type: Standoff - Exclude from BOM: false - Manufacturer Name: RAF Electronic Hardware - Datasheet URL: http://dpk3n3gg92jwt.cloudfront.net/domains/raf/pdf/RAF%20Catalog.pdf - Manufacturer Part Number: M2106-2545-AL **Pins:** - P1 [pin 1] ### H3 — [M2106-2545-AL](https://www.flux.ai/vasy_skral/m2106-2545-al.md) - Part Type: Standoff - Manufacturer Part Number: M2106-2545-AL - Exclude from BOM: false - Manufacturer Name: RAF Electronic Hardware - Datasheet URL: http://dpk3n3gg92jwt.cloudfront.net/domains/raf/pdf/RAF%20Catalog.pdf **Pins:** - P1 [pin 1] ### H4 — [M2106-2545-AL](https://www.flux.ai/vasy_skral/m2106-2545-al.md) - Part Type: Standoff - Datasheet URL: http://dpk3n3gg92jwt.cloudfront.net/domains/raf/pdf/RAF%20Catalog.pdf - Manufacturer Name: RAF Electronic Hardware - Exclude from BOM: false - Manufacturer Part Number: M2106-2545-AL **Pins:** - P1 [pin 1] ### IC1 — [INA219AIDCNR](https://www.flux.ai/vasyl/ina219aidcnr.md) - Manufacturer Part Number: INA219AIDCNR - Part Type: Integrated Circuit - Manufacturer Name: Texas Instruments - Datasheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Fina219 **Pins:** - A0 [pin 7] - A1 [pin 8] - GND [pin 3] - SCL [pin 5] - SDA [pin 6] - VIN- [pin 2] - VIN+ [pin 1] - VS [pin 4] ### Q1 — [IRFZ44NPBF](https://www.flux.ai/adrian95/irfz44npbf.md) - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Name: Infineon Technologies - Manufacturer Part Number: IRFZ44NPBF - Datasheet URL: https://www.infineon.com/dgdl/irfz44npbf.pdf?fileId=5546d462533600a40153563b3a9f220d - Part Type: Transistor **Pins:** - D [pin 2] - G [pin 1] - S [pin 3] ### RPi1 — [Raspberry Pi 2 3 4 5 Model B](https://www.flux.ai/vasy_skral/raspberry-pi-2-3-4-5-model-b.md) - Part Type: Connector **Pins:** - ~CE0~/GPIO8 [pin 24] - ~CE1~/GPIO7 [pin 26] - 3V3 [pin 17] - 3V3 [pin 1] - 5V [pin 4] - 5V [pin 2] - GCLK0/GPIO4 [pin 7] - GCLK1/GPIO5 [pin 29] - GCLK2/GPIO6 [pin 31] - GND [pin 34] - GND [pin 6] - GND [pin 9] - GND [pin 30] - GND [pin 25] - GND [pin 14] - GND [pin 20] - GND [pin 39] - GPIO14/TXD [pin 8] - GPIO15/RXD [pin 10] - GPIO16 [pin 36] - GPIO17 [pin 11] - GPIO18/PWM0 [pin 12] - GPIO19/MISO1 [pin 35] - GPIO20/MOSI1 [pin 38] - GPIO21/SCLK1 [pin 40] - GPIO22 [pin 15] - GPIO23 [pin 16] - GPIO24 [pin 18] - GPIO25 [pin 22] - GPIO26 [pin 37] - GPIO27 [pin 13] - ID_SC/GPIO1 [pin 28] - ID_SD/GPIO0 [pin 27] - MISO0/GPIO9 [pin 21] - MOSI0/GPIO10 [pin 19] - PWM0/GPIO12 [pin 32] - PWM1/GPIO13 [pin 33] - SCL/GPIO3 [pin 5] - SCLK0/GPIO11 [pin 23] - SDA/GPIO2 [pin 3] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/klong4/raspberry-pi-4-hat-template](https://www.flux.ai/klong4/raspberry-pi-4-hat-template).* --- *Generated from [https://www.flux.ai/klong4/raspberry-pi-4-hat-template](https://www.flux.ai/klong4/raspberry-pi-4-hat-template)*
