MAX21000 Evaluation
Board Adapter
General Description
The MAX21000 evaluation board (EV board) adapter
provides the hardware necessary to easily connect the
MAX21000 ultra-accurate, low-power, 3-axis digital output
gyroscope to an existing system.
The EV board includes a MAX21000 installed on a removable PCB, an LDO regulator, and jumpers.
A USB pen is provided with the EV board that contains
the schematics and C library file to easily integrate the
device into the system.

Quick Start
Jumper Descriptions
Required Equipment
P1 Jumper
● System able to communicate through the I2C or SPI
interface
P2 Jumper
● MAX21000 EV board adapter
● 1.8V to 5V power supply
The P1 jumper is used to set the supply to VDD_CORE
and VDD_IO (see Table 1 for P1 jumper settings).
The P2 jumper is used to set the CS pin if the I2C
interface is used (see Table 2 for P2 jumper settings).
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
I2C.
1) Using connector P4, connect to SPI or
If
used, the P2 and P3 jumpers must be inserted.
I2C
is
2) Supply the EV board adapter through the P4 connector, providing directly VDD_CONN and VDD_IO.
P3 Jumper
The P3 jumper is used to set the SA0 pin if the I2C
interface is used. This changes the last bit of the slave
address for I2C protocol (see Table 3 for P3 jumper settings).
3) Set the P1 jumper for the desired supply to VDD_
CORE.
4) Set the value of VDD_CONN and VDD_IO accordingly
to the P1 jumper.
5) The device is now able to communicate with the
system.
