NASA Open Source Rover - Voltage Divider board Rev C

NASA Open Source Rover - Voltage Divider board Rev C

Created by pcbsio on 2018-10-10 18:04:16

2 Layer Board - 3.8645 sq in (1.7850in x 2.1650in) / 2493.22 sq/mm (45.34mm x 54.99mm)
$14.84 per set of 4 ($3.84 per sq in)

The purpose of this board is to solve the mismatch between the encoder logic levels and what the motor controller expects as encoder inputs. The absolute encoder outputs a signal from 0-5V based on the position of the encoder shaft, but the motor controllers expect in a signal that is 0-2V. To make this transformation, we will create a linear voltage divider.

NASA Open Source Rover - Logic Shifter board Rev B

NASA Open Source Rover - Logic Shifter board Rev B

Created by pcbsio on 2018-10-10 18:03:43

2 Layer Board - 4.0466 sq in (2.5450in x 1.5900in) / 2610.7 sq/mm (64.64mm x 40.39mm)
$15.54 per set of 4 ($3.84 per sq in)

This board is made to handle the mismatch between the digital logic voltage level of the Raspberry Pi and the LED matrix. Digital logic is typically at either 3.3V or 5V. The GPIO pins on the Raspberry Pi will output at the 3.3V logic, and the LED matrix is made to read at 5V digital logic levels. In order to have these signals make sense to each other we use a device called a logic shifter, which will take the 3.3V signals and turn them into 5V signals.

NASA Open Source Rover - Serial Splitter Board Rev A

NASA Open Source Rover - Serial Splitter Board Rev A

Created by pcbsio on 2018-10-10 18:03:14

2 Layer Board - 0.8492 sq in (1.1100in x 0.7650in) / 547.87 sq/mm (28.19mm x 19.43mm)
$3.40 per set of 4 ($4.00 per sq in)

This board is to pass the serial read and write lines, as well as +5V/GND from the Raspberry Pi to each of the motor controllers without having to solder wires to split each of these individually.

2 Layer Board - 44.5094 sq in (9.4134in x 4.7283in) / 28715.68 sq/mm (239.1mm x 120.1mm)
$145.10 per set of 4 ($3.26 per sq in)

The main features are (for now):

  • 50 key button matrix
  • 4 clickable color coded encoders
  • 1W Audio amplifier for the internal speaker
  • Battery management and charging circuit for the lipo/li-ion batteries and a led battery meter
  • Gpio breakout to allow to position the Raspberry rotated 90 degrees to access the USB ports and to easely use both the LCD screen and the audio card.

2 Layer Board - 3.7000 sq in (2.0000in x 1.8500in) / 2387.09 sq/mm (50.8mm x 46.99mm)
$14.21 per set of 4 ($3.84 per sq in)

This is the FeatherWing Doubler - a prototyping add-on and more for all Feather boards. This is similar to our FeatherWing Proto except there are two! The magic of the Doubler comes when stacking a Feather and another board on top of the Doubler so you can work with both boards simultaneously side-by-side!

The Doubler has a duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. Also, the two sets of pins are cross connected and for GND and 3.3V, we give you a full strip of connected pads.

PCBs.io Perma-Proto HAT - Designed by Adafruit

PCBs.io Perma-Proto HAT - Designed by Adafruit

Created by pcbsio on 2017-09-01 13:16:28

2 Layer Board - 5.6925 sq in (2.5591in x 2.2244in) / 3672.57 sq/mm (65mm x 56.5mm)
$21.29 per set of 4 ($3.74 per sq in)

The PCBs.io Perma-Proto HAT has a grid of 0.1" prototyping soldering holes for attaching chips, resistors, LED, potentiometers and more. The holes are connected underneath with traces to mimic the solderless breadboards with which you're familiar. There's also long power strips for +3V, +5V and Ground connections to the Pi. Near the top we break out nearly every pin you could want to connect to the Pi (#26 didn't quite make the cut).

2 Layer Board - 5.6000 sq in (2.0000in x 2.8000in) / 3612.9 sq/mm (50.8mm x 71.12mm)
$20.94 per set of 4 ($3.74 per sq in)

This is the FeatherWing Tripler - a prototyping add-on and more for all Feather boards. This is similar to our FeatherWing Proto except there are three! The magic of the Tripler comes when you want to connect your Feather to two other Feather Wings without needing any stacking headers!

The Tripler, like the Proto, has three breakouts for each pin on a Feather, as well as a bunch of plain grid proto holes. Also, the three sets of pins are cross connected and for GND and 3.3V, we give you a full strip of connected pads.

You'll need to solder on the female headers to the PCB.

Assembled Dimensions: 71.25 x 51 x 12 mm / 2.8" x 2" x 0.46"
