The MAX32630 Feather is a development board from Maxim Integrated based on the MAX32630 ARM Cortex-M4F microcontroller. The board is compatible with Adafruit Feather boards and most FeatherWings to maximize its capabilities, and comes with a number of onboard periperhals, as well as a six-axis inertial sensor and RGB LED.
MAX32630 Feather projects start with the following sensor elements imported from the Element Library:
Some devices may have limitations or design restrictions that cause unexpected behavior when used with Atmosphere. Specific information and details pertaining to the MAX32630 Feather and its performance on Atmosphere is noted below.
- All analog pins have a reference voltage of 1.8v
Default Pin Mapping
Atmosphere configures each peripheral to a default pin for every supported device, based on ideal pairing of pins and their usage. The default pin configuration is set for convenience and enables each peripheral to work naturally without needing to be modified.
All pins can be used as general purpose input/output (GPIO) unless otherwise specified.
MAX32630 Feather projects start with the following pin configuration:
||Analog Input 0|
||Analog Input 1|
||Analog Input 2|
||Analog Input 3|
This kit has no pin labels, so use the internal pin port and number to reference the pin.
Internal MAX32630 Feather
The MAX32630 Feather is compiled using the MBED SDK. Each GPIO pin can be accessed using the following nomenclature:
P[PORT]_[PIN]. For example, Port 5 Pin 7 (I2C2 SDA) can be accessed with
The default pin for any peripheral can be changed within an element's properties, from an element that references that particular peripheral.

Programming the MAX32630 Feather involves downloading its project firmware from Atmosphere Studio and directly transferring it to the device over USB. However, unlike many devices supported in Atmosphere, the MAX32630 Feather doesn’t contain a built-in programmer. Instead you must use a MAXREFDES100HDK Programming Adapter or external DAPLink to program the device.
In order to program a MAX32630 Feather, ensure you have the following initial setup configuration:
- Connect the fine 10-pin ribbon from the SWD (J3) header on the MAXREFDES100HDK to J4 on the MAX32630 Feather.
- Connect the MAX32630 Feather to a power source via micro USB.
- Connect the MAXREFDES100HDK to the computer via its micro USB connector labeled HDK.
When connected, the MAXREFDES100HDK will expose itself as a drive labeled “DAPLink.”
You may need to update the board's native firmware in order to program the MAX32630. For information on performing a firmware update, see the official MBED MAXREFDES100HDK docs.
With the initial setup finished, complete the remaining setup configuration steps:
- The MAX32630 Feather is connected to the computer via USB.
- The project to be programmed has been compiled.
With setup complete, you can program your MAX32630 Feather:
- From Atmosphere Studio’s Embedded tab, click the button from the tab’s toolbar. This downloads a .bin file containing the project’s compiled firmware.
- Locate the downloaded file on your computer, and move it into the DAPLink drive. This initiates programming of the MAX32630 Feather.
- Once programming is finished, the DAPLink drive will unmount and then mount again indicating programming is complete. Then press the board’s reset button to start your application.
When complete, the MAX32630 Feather is programmed with the project’s embedded firmware.
