  • Attending: @Darwin Clark @Jack Greenwood @Aidan Bowers (Deactivated) @Ethan Abraham @Christopher Chung

  • Agenda

    • Desired features of ZP3 interface board Rev. 1

Proposed (EE)

Proposed (FW)

Final

Proposed (EE)

Proposed (FW)

Final

Every IO pin (~45) broken out

  • Header: 2.54mm standard male pins (female?)

  • Make sure to get 3v3

  • Make sure to get 5v

    • multiple

  • NOT VBat

  • Pad beside header for oscope

    • Multiple

  • NOT VBat

  • Pad beside header for oscope

  • For PWM pins, break some (all?) out in a servo standard (signal power ground)

  • Group UART with power, TX, RX, ground

  • Very explitily labeled groups

  • No power + gnd for SPI and I2C, just the data pins

  • LEDS to unused GPIOs

Power and Interlock LED

@Darwin Clark Will look into how possible this is

 

LEDs or indicator on all comm lines (Data lines of UARTs, I2C, SPI, PWM) ++

 

 

MicroSD card pins

 

MicroSD card pins break out

Pot, selectibly tied to analog input pin via header

 

 

 

Easily accessable ground (screwholes or on isolated male pin)

Easily accessable ground (screwholes or on isolated male pin)

 

 

In general making sure that things arn’t clumped together such that one is touching pads together

 

 

 

Flight Board niceities

  • @Darwin Clark (fixture this out) Putting simulator connector for simulator board on both flight and dev board

  • @Christopher Chung Figure out weather or not timer pins are bidirectional and which ones are used for PPM on ZP3.0 sch

Rev n Features

Instructions: If you have ideas for a feature that should be present on a future revision of ANY interface board, list them here and what board it is applicable too (E.G rev 2 of dev interface, flight interface, ect.)

  • Idea 1

  • Ect…

 

Assembly Notes

When soldering the Molex slimstack connectors to the primary and interface boards, make sure the notch and th top and bottom of the connector is on the right side as shown in the diagrams.

You can visualize that if the interface board was flipped over, the notches in the connectors on the interface board would fit into the spaces on the left side of the connectors on the primary boards.
