ALLEGRO A89211-A89212 Evaluation Board
DESCRIPTION
The A89211 or A89212 (A89211/2) evaluation board is a high-performance processor with integrated three-phase gate driver and precision current-sense capability. The evaluation board facilitates advanced control of three-phase brushless direct current (BLDC) and permanent-magnet synchronous-motor (PMSM) motors through graphical user interface (GUI).
FEATURES
- Three phase BLDC motor connection
- USB-C and FTDI chip for universal asynchronous receiver/transmitter (UART) communication with GUI for motor control
- Potentiometer to test analog-to-digital converter (ADC)
- General-purpose input/output (GPIO) connection socket
EVALUATION BOARD CONTENTS
- APEK89211 or APEK89212 evaluation board
- Universal debugger daughterboard
Table 1: A89211/2 Evaluation Board Configurations
| Configuration Name | Part Number | Minimum Voltage (V) | Maximum Voltage (V) | Phase Current (A) |
| A89211 Evaluation Board | APEK89211GEV-T | 8 | 48 | 30 |
| A89212 Evaluation Board | APEK89212GEV-T | 8 | 72 | 30 |
Table 2: Product Family Board Configuration
The board supports the A89211/12 product family and comes preconfigured for the 5 V variant For the other variants, purchase component U1 separately and configure the board according to this table.
| 5 V Variant
(Default Board Configuration) |
The board is delivered with this default configuration.

USING THE EVALUATION BOARD
The default board jumper positions are configured for motor control operation with the GUI through USB-C connection. The correct jumper positions for both the A89211/2 evaluation board and the debugger daughterboard are provided in the Motor Control Quick Starter Guide. To download the guide and other items required for the desired application—such as motor control, example code for peripherals, hardware manuals, etc.—see the Related Links section. The features of the A89211/2 evaluation board are shown in Figure 2.
The debugger daughterboard is shown in Figure 3. When con-necting the debugger daughterboard to the A89211/2 evaluation board, ensure the arrows are aligned. This indicates the correct orientation for the debugger daughterboard.
- Ensure the debugger daughterboard dip switch, S1, switches 1 and 2, are set to the off position.
- A debugger that supports SWD connection, such as ULINK2 or ULINKplus, must be connected to the debugger daughter-board.
