Required Equipment
•
MAX32690FTHR Board containing a MAX32690 with a Preprogrammed Demo
•
One USB Standard-A to USB Micro-B Cable
Procedure
The FTHR board is fully assembled and tested. Use the following steps to verify board operation:
1. While observing safe ESD practices, carefully remove the board from its packaging. Inspect the board to ensure that
no damage occurred during shipment. Shunts are preinstalled before testing and packaging.
2. The target microcontroller is preprogrammed with the demo code. To run the demo, power up the board by plugging
the USB cable into the Connector J5. Connect the other end of the USB cable to a computer or power adapter.
3. Once power is applied to the board, the demo automatically starts and begins flashing RGB LED D1. This indicates
that the microcontroller is executing code and that the simple demo is running as expected. The demo also sends a
"Hello World" message followed by a counter. To view this message, connect the MAX32625PICO (included in the
box) to the SWD connector (J4) on the MAX32690FTHR board. Then, set up a serial terminal at 115200 baud rate on
the MAX32625PICO board's COM port.
Now that the programmed demo has run successfully, the next step is to visit the MAX32690 solution center at
developer.analog.com.
MAX32625PICO Debugger
A MAX32625PICO debugger is provided for programming and debugging the target microcontroller through the SWD
interface. Furthermore, the MAX32625PICO also serves as a UART bridge, providing serial terminal functionality without
the need of an additional USB cable.
This FTHR kit includes a USB cable for connecting the MAX32625PICO debugger to a PC and a ribbon cable for
connecting the MAX32625PICO debugger to J4 of the EV kit.

Detailed Description of Hardware
Power supply
The FTHR board is powered by +5V through V
PMIC and LDO regulators. The PMIC (MAX77654) generates the +1.8V, +3.3V, and BLE_LDO_IN voltages required by
the MAX32690 using its integrated buck converters and LDO. It is also capable of charging a Li-ion battery (not included)
connected to the J3.
In addition to the PMIC, two LDOs generate the +1.1V V
PMIC is capable of generating these voltage levels, additional LDOs are used to ensure proper USB functionality and
power-up/power-down sequencing.
The MAX8511 (U6) ensures that the V
the MAX8561(U4) is used to ensure the correct sequencing of the V
