+## Teensy 4 version
+
+This is a port for Teensy4.0, it uses a connection PCB to reroute signals to the Teensy3.2 footprint. The board adapter is in kicad format.
+On the Teensy4, you can lower the frequency to 150Mhz and it works.
+A second can, CAN2, is available on Teensy4.0 to add functionalities or to resolve CAN speed conflicts.
+
+Uncomment //#define USING_TEENSY4 in config.h and select Teensy4.0 as board to use it.

+Adapter to use a Teensy4.0 board with the simpBMS in place of the Teensy3.2.
+
+Mostly all pins are the same, but CAN1 must be rerouted. And the Teensy4.0 UART3 is used as Teensy3.2 UART2.
+The firmware is modified to take the rerouting into account.
+The source code modifications are under the USING_TEENSY4 directive.
+
+The schematic is drawn with kicad 7.0 and under the Apache licence
+
+Note that this is just a proof of concept, the schematics of the carrier board could be adapted to add a CAN bus or two.
