DigiKey Parts list for a single module

Assembly Tips

To simplify the construction the following assembly order is recommended:

• U2 is inserted from the bottom. It also has to be soldered from the same side as the chip. The excess pins on the top side can either be trimmed off or bent over - make sure they do not touch.
• The CTS 2180 ETAME IC pins are then soldered on to the board. The easiest method is to use an empty IC socket on the M100 to make sure they are the correct length.
• U1 is the last part to be placed on the board.

How to use the IC Pins (CTS 2180)

The suggested pins used for inserting the module into the M100 IC socket are similar to IC pins and should not cause any problems with the socket. The pins are used in a slightly different way to the usual method shown in their datasheet, they are normally used for mounting SIL boards vertically via their edge.

1. Cut a strip of pins to the required length, 14 pins per side in this case. Leave on the top and bottom rails.
2. Snip the pins off close to the bottom rail trying to keep them the same length.
3. With one row of holes aligned with the socket insert the pins from the top through the PCB holes into the socket pins. Make sure the pins are firmly pressed into the socket. This will give the required length of pins for the socket. Repeat for the other side of the module.
4. Solder the pins on the top of the PCB. Once all the pins are soldered the PCB can be removed from the socket.
5. Snap off the top rail (it will breakaway) and snip off the pin heads close to the top of PCB to leave a clean surface on the top of the board. The pin tops can be resoldered to provide a better finish if desired.

MCP2562 Breakout Board Mk.2

2 layer board of 0.60 x 0.60 inches (15.3 x 15.3 mm).
Shared on April 18th, 2018 04:10

Description

Simple breakout board to convert logic-level signals to CAN bus. The MCP2562 is nothing but a fancy level shifter and must be used with a CAN bus controller, such as a Microchip MCP2515.

This board fits in a breadboard!

The left-side pins are the same as the CAN bus header on the LPCXpresso11C24 dev board.

Designed in EagleCAD.

Pins

Right side:

• TX: data out from CAN bus
• RX: data into CAN bus
• GND: ground (same as left side)
• +5V: powers chip (same as left side)
• VIO: interface voltage reference
• STBY: place the MCP2562 into low-power state

Left side:

• CANH: high-voltage side of CAN bus (usually 2.5-5V logic)
• CANL: low-voltage side of CAN bus (usually 0-2.5V logic)
• GND: ground (same as right side)
• +5V: transceiver power rail (same as right side)
• STBY: place the MCP2562 into low-power state

BOM

• U1: Microchip MCP2562SN
• C1, C2: 0.1µF 0603 ceramic capacitor
• R1: 120Ω 0603 resistor

Honeywell MPR Breakout Board

2 layer board of 0.60 x 0.40 inches (15.3 x 10.2 mm).
Shared on April 18th, 2018 04:10

Description

Simple breakout board for Honeywell’s MPR line of pressure sensors, which use a Wheatstone bridge and an optional 1nF filter capacitor.

This board has 0.5" pin row spacing such that it fits in a standard breadboard.

Designed in EagleCAD.

Pins

Right side:

• RST: reset, active-low
• EOC: end of conversion, data is available, active-high
• GND: ground
• +3.3V: VDD (note: device has no reverse-polarity protection and very little over-voltage protection)

Left side:

• MISO: master-in-slave-out for SPI
• SCL/SCK: clock input for SPI and I2C
• MOSI/SDA: data input for SPI, data I/O for I2C
• CS: chip select for SPI

BOM

• top footprint: any Honeywell MPR device
• 100nF: any 100nF 0603 capacitor
• 1nF: any 1nF 0603 capacitor
