SAMD21J18 is a flexible, easy-to-use, low-power consumption Microchip SAM D21 Arm® Cortex®-M0+ based
microcontroller and the ideal host controller for the MTB. It drives all supported
communication protocols from the client and transfers data to the PC side and vice
versa. Host firmware can be programmed to SAMD21 using drag and drop programming.
Connect the MTB via USB to a Windows® 10 PC and drop
a .hex file onto the created drive for drag and drop programming.
Alternatively, use an MCHP external debugger like Power debugger, Atmel-ICE via SWD header J1.
Use MPLAB Discover to download the latest firmware for the MTB with features added by Microchip over time.
