The PCB was modified to connect what came into PF0 before to PA10, this Microcontroller, and has to be enabled by the SB12 jumper). PF0 pin on the header of the Discovery board is not connected to the On pin PF0, but this pin is occupied by an 8MHz clock signal that comesДЇrom the STLink microcontroller on the STM32F3 discovery (U2) and can'tД«e changed without slowing down the main microcontroller (the actual The SDA pin from I2C2 (Used for the MD03 boards) was previously located

V2 of the PCB is the one that was manufactured and is found on Kauil, while doing the code implementation of it we found several problems with the design that had to be corrected for the system to work, the following list explains them, and the fix that was applied, future versions of the board should have them permanently fixed. jpg image with the schematics used for the PCB, for easy acces for people that do not have DipTrace.

Schematic.dch: A DipTrace file with the schematic for the PCB, it contains information about logical connections of the board.

jpg image of the PCB for quick reference without requiring DipTrace

PCB.dip: A DipTrace file with the PCB layout and routing.

Lib: This folder contains library files for DipTrace with all schematic components and PCB patterns used on the PCB, we do not use any external library besides the one provided by DipTrace and the ones found here, so the design is portable.

Gerbers: This folder contains the files that were sent to the manufacturer to produce the actual PCB, they were exported from DipTrace.

BOM: This folder contains some spreadsheets with components used for the PCB, costs and suplier links.

Inkscape, update the png and pdf versions and commit the changes. To modify any of these diagrams clone the repository, edit the svg file locally with The regulator shuts down maybe due to a high peak current at startup, most of the times disconnecting and Note: We've noticed that sometimes when connecting the battery to the regulator in which the Hokuyo is connected Which does not appear in the diagram because it has its own battery and is connected directly). Regulators that power up the cameras because they are the components that consume the most power (after the CPU The next diagram shows how the Power sources are distributed within the PCB, care was taken to separate the It's also important to note the red ports that mark issues found while using the board and how they were fixed,ДЇor more information on these see Known-issues. The following diagram shows which pins from the microcontroller are connected to which components on the board, Almost any pin can be set to be a GPIO pin if its specific functionality is not required.All UART, I2C and SPI connectors have GND and power pins according to the supported voltage to ease theД¬onnection of devices with just one connector and one cable.4 ADC pins exposed to connectors to sense data from various sources.

3D gyroscope, 3D magnetometer and 3D accelerometer provided by the STM32F3 discovery board.

One connector for an I2C to USB interface in case communications get saturated over the microcontroler's USB.

USB communication directly from the microcontroller.

4 I2C external connectors, one pair per I2C peripheral on the microcontroller.

4 SPI connectors (2 of them 5V tolerant), two connectors per SPI peripheral from the microcontroller with the.

Analog multiplexer with a voltage divider to measure the voltage of all 5 batteries connected, plus 2 optionalД®xternal signals while using just one ADC.

DIPTRACE EXTERNAL PINS DRIVER

Driver circuit to read a button so it can be used as an emergency stop.

Driver circuit for a Buzzer to serve as a low battery alert.

Specific purpose connectors, 2 for the MD03 boards and 2 for the encoders.

The board is for the most part an interface to the various peripherals available on the STM32F3 microcontroller,Д«ut there are also some specific functionalities that should be noted, the is a summary of what the PCB has:

The design files were made using DipTrace which can be downloaded freely for 30 days, or without time limitations but with a 300 pin limitation (this design contains more than 300 pins). Also it should be easy for new students joining the team to start developing for it, this is why we choosed to use the same development board as a core as the one used in the microcontroller (embedded systems) class, the STM32F3 discovery. The main motivation behind the desigh of this PCB is to have a platform for testing and implementing new hardware easily. This repository contains the design files for the PCB found on Kauil.
