Teensy 3.6 3.3-5v voltage level shifter for Speeduino (or Arduino Mega layouts)

VERIFY THAT YOUR SHIELD/HARDWARE AND CODE WILL WORK WITH THIS ADAPTER BEFORE USAGE!

NOTES:

-For more information, please read the product instruction and specification sheet in the ‘Support’ section.

-This board will work with Teensy 4.1, however I/O count is reduced due to differences in pinouts between the 3.6 and 4.1.

-The pinout table above is for users using the Teensy 3.6 only! Please check your device pinouts before ordering.

Looking to add more processing power to your Speeduino setup? Want to use 5V components with your 3.3V Teensy? This adapter board allows for the usage of 3.3V Teensy MCU boards with older 5V Arduino and Arduino MEGA compatible shields and hardware. It is based around the TXB0108 IC which allows for bidirectional level shifting at high speeds. The analog voltage conversion is handled by a pair of LMV324 ICs. The pinout for the boards is 1:1 with the Arduino MEGA, with the exception of the pin assignments noted in the table on the back of the board (see listing picture).

One can order the board with or without external pin headers for the MEGA hardware. The pin headers are stackable for ease-of-use.

Teensy + Teensy headers are sold separately.
