7 Removing and Installing Supported Motor Drivers
The EVM can support the DRV8210/8212/8220DSG, DRV8210/8212PDSG, and DRV8210/8212/8220DRL
devices. The EVM contains two footprints that can support the devices listed above. Footprint U2 supports the
DSG and PDSG devices and footprint U5 supports the DRL devices. U2 and U5 share the same output
connector so only one of the two footprints should be populated at any time. Below are step-by-step instructions
on how to remove and place different drivers on the EVM:
1. Disconnect power from the EVM.
2. Carefully de-solder the device from the PCB. Make sure to follow proper soldering and ESD protection
procedures to prevent damage to the EVM.
3. Carefully solder the new device to the EVM. See
for further instructions. Visit
authorized third party vendor to purchase the desired driver.
4. The EVM uses a combination of resistors to identify the device that is populated on the board.
show the resistors used for device identification. The MCU reads the values of ID1, ID2, and ID3 to determine
the device that is installed on the EVM. The firmware will function slightly different depending on the device
that is on the board. Each of the supported devices have unique values for ID1, ID2, and ID3 which are set by
R5, R7, R8, R9, R13, and R14. After installing the new device, make sure to populate the appropriate
resistors.
show the unique device ID for each supported device and the resistor combination to
populate.

Soldering procedures
DRV8210/8212DSG or DRV8210/8212PDSG
•
Solder the device to footprint U2. Make sure pin 1 of device aligns with the dot on
the PCB
•
If not already de-populated, de-populate R10
•
If not already populated, populate C6 (1210, 25V, 22µF), C9 (1210, 25V, 22µF),
C3 (0402, 25V, 0.1µF), C1 (0603, 25V, 0.1µF), and R15 (0603, 0Ω)
DRV8220DSG
•
Solder the device to footprint U2. Make sure pin 1 of device aligns with the dot on
the PCB
•
If not already de-populated, de-populate R15
•
If not already populated, populated C6 (1210, 25V, 22µF), C9 (1210, 25V, 22µF),
C3 (0402, 25V, 0.1µF), C1 (0603, 25V, 0.1µF).
•
If not already populated, populate J7 (2x1, 2.54 mm, TH header). See
to
learn about the function of J7 header.
DRV8210/8212/8220DRL
•
Solder the device to footprint U5. Make sure pin 1 of device aligns with the dot on
the PCB.
•
If not already de-populated, de-populate C6, C9, C3, C1, R10, and R15.
•
If not already populated, populate C10 (0402, 25V, 0.1µF).
