=====
|
||||
|
||||
<img src="https://github.com/commaai/neo/blob/master/neo.png">
|
||||
|
||||
The neo is an open source robotics research platform. It is powered by a OnePlus 3 smartphone and an [STM32F205](http://www.st.com/en/microcontrollers/stm32f2x5.html?querycriteria=productId=LN1433)-based CAN interface board, in a 3d-printed housing with active cooling.
|
||||
|
||||
The neo platform includes [NEOS](https://github.com/commaai/neo/releases/tag/swag), a stripped down Android ROM designed for robustness and to get out of the way of your software. It also provides a modern linux environment for easy development.
|
||||
|
||||
Why
|
||||
------
|
||||
|
||||
You cannot get a higher performance embedded processor than what's shipping in modern smartphones. They also come with an impressive array of sensors and radios, and are very low cost.
|
||||
|
||||
For some background see the work of [Android Based Robots](http://www.socsci.uci.edu/~jkrichma/ABR/abr_background.html).
|
||||
|
||||
Build
|
||||
------
|
||||
|
||||
The neo is designed to be very easy to construct. You need to be able to shop online and use a soldering iron.
|
||||
|
||||
There is a **[very detailed guide](https://github.com/commaai/neo/raw/master/guide.pdf)** with instructions on what to order and how to build a neo.
|
||||
|
||||
to build a neo, 6 orders must be placed from the following sources:
|
||||
- digikey
|
||||
- mcmaster
|
||||
- shapeways
|
||||
- oshpark
|
||||
- amazon
|
||||
- oneplus
|
||||
|
||||
The total cost is about $700.
|
||||
|
||||
|
||||
Directory structure
|
||||
------
|
||||
|
||||
- board -- EagleCAD schematic, board, and library files
|
||||
- parts -- csv bill of materials
|
||||
- case -- stl files for 3d printing
|
||||
|
||||
|
||||
Licensing
|
||||
------
|
||||
|
||||
neo research platform is released under the MIT license.
|
||||

||||

build notes
|
||||
|
||||
1. solder U1 onto the front of the board and check for any shorts between pins, this is
|
||||
the microcontroller that interacts with the OnePlus3
|
||||
|
||||
2. solder C1-13 in any order onto the front of the board
|
||||
3. solder R1, R2, R7, R8, R11-13 onto the front of the board
|
||||
4. solder Q1 onto the front of the board, this controls the speed of the fan
|
||||
5. solder U3 onto the front of the board, this is the CAN transceiver
|
||||
6. solder U4 onto the front of the board, this is the 5V to 3.3V converter
|
||||
7. solder Y1 onto the front of the board, this is the main crystal resonator
|
||||
8. optional for uart debug: fashion J1 by breaking away 6 pins from the 40 pin
|
||||
|
||||
connector then solder onto the back of the board, this is the uart breakout
|
||||
connection
|
||||
9. solder J2 onto the back of the board with the notch on the right (see image
|
||||
below), this is the connector for the fan
|
||||
10. solder J3 onto the back of the board, make sure it remains level with the board so
|
||||
that the otg usb cable will lay flat when connected
|
||||
11. solder J4 onto the back of the board, make sure the plastic legs are fully snapped
|
||||
into their holes, this is the breakout to the research vehicle
|
||||
12. J5 is used externally from the board, put it aside for later
|
||||
13. solder LED1 and LED2 to the back of the board, note that the green and red
|
||||
LEDs do not have the same polarity so if they are mixed up they will not operate
|
||||
properly
|
||||
14. solder R3-6, R9, R10, R14, R15 onto the back of the board
|
||||
15. solder SW1 onto the back of the board, this is used to put the microcontroller into
|
||||
DFU mode to flash the initial firmware (should not be required for future firmware
|
||||
flashes)
|
||||
16. bend pins of C14 before soldering so that the curved surface lays on the back of
|
||||
the board (see image below)
|
||||
17. solder C15 onto the back of the board
|
||||
18. solder U2 onto the back of the board, this is the 12V to 5V power supply
|
||||
19. go to page 14 and build the breakout cable in order to test the board
|
||||
|
||||

|

|
||||
breakout cable
|
||||
|
||||
1. cut off ~8” of the cat6 cable and strip the internal wires
|
||||
2. for a Honda vehicle, make the connections in the JAE column (for all other vehicles
|
||||
|
||||
make the connections show in the OBDII column)
|
||||
3. cover the back of the JAE (or OBDII) connector with hot glue in order to prevent any
|
||||
|
||||
shorts or breaking of wires
|
||||
note: you can build an AC-DC adapter using the 12V power supply mentioned on page 3.
|
||||
|
||||
this is useful for using a neo outside a car environment.

|

test the board
|
||||
|
||||
1. check for any shorts between the pairs of points shown below, fix if any exist
|
||||
2. setup the OnePlus3 with NEOS by following the instructions at
|
||||
|
||||
github.com/commaai/one/tree/master/neos
|
||||
3. plug the female end of the OTG USB cable into the board and the USB C
|
||||
|
||||
connector into the OnePlus3
|
||||
4. plug the rj45 connector into the board and hold down SW1 while you plug the
|
||||
|
||||
breakout cable into the car (or 12V adapter), this puts the microcontroller into
|
||||
DFU mode
|
||||
5. the OnePlus3 will upload the firmware to the microcrontroller, if the red LED
|
||||
on the board begins to flash then your board is working properly
|
||||
6. if you have any issues or submit an issue request at
