Teensy 4.0 Low Profile

Description

For the vertically challenged, the Teensy 4.0 Low Profile is assembled with very short low profile male header pins and shipped along with the mating low profile female header sockets for installation into a PCB.  This header arrangement allows for a minimal installed height of the Teensy 4.0 for fitting into low profile enclosures or fitting under something such as an LCD for a compact layout.

This version of Teensy 4.0 is built to order and will normally ship within 1 to 2 business days.

Note:  The short male header pins prevents this version of Teensy 4.0 from plugging into a standard solderless breadboard.  These are typically used with a custom PCB or solder type proto board with the matching mating female sockets.

Package Includes:

• Teensy 4.0 configured with low profile male header pins
• Qty 2 – Mating female low profile header socket
• Handy pinout diagram

The female header socket is 3.5mm  (0.14″) tall and the contacts have a gold flash.

The male header pin are 2.54mm (0.1″) long with a gold flash and have a 2.5mm (0.1″) tall plastic body.

When these headers are stacked, the combined height is about 6.1mm (0.24″) compared to 11mm for the standard length header/socket combo.  This saves about 5mm (0.19″ in height as shown in the picture below.  Even with a relatively short contact area, the headers mate with a solid mechanical and electrical connection.

Low Profile Header Comparison to Standard Header

The total stack-up from the baseboard to the top of the Teensy USB connector which is the highest point on the Teensy is 10.6mm as shown below.  The picture shows a Teensy 4.1, but the stack-up is the same.

Low Profile Header Stack-up with Teensy

Note:   The picture shows spring-loaded POGO pins connecting to the USB pads on the bottom of the Teensy so that the USB can be routed to the edge of the board since the Teensy will be inaccessible in this particular application.  In this case, it also allowed the USB connector type to be converted to USB-C.  A good POGO pin height for use with these headers is 7.5mm.

If you need the 1×5 ON/OFF/Program/VBAT header added as well, add that note to the Order Notes section when you go to checkout and it will be added at no additional cost along with the mating female 5-pin header socket.

Before they are shipped, these modules are:

• Base Teensy inspected and tested by PJRC
• Low profile male header pins soldered on
• 5-pin ON/OFF/Program/VBAT header soldered on to bottom of Teensy (if requested by customer)
• Flux cleaned
• Packaged in resealable ESD bag for safe storage along with mating female header sockets.
