1 Out of the Box

The TMF882X-SHIELD board is an Arduino UNO form factor development platform for quick

evaluation of the TMF8820, TMF8821 & TMF8828 multi-zone dToF sensors.

Featuring a small (20 mm x 12 mm) sensor breakaway board, this kit can be easily integrated into

custom, prototype hardware.

Several cover glass and air gap spacers are provided, this helps to evaluate the system for optimal

optical performance.

2 Software Installation

The TMF882X-SHIELD is designed to operate with a variety of MCU hardware platforms.

A Software Development Kit (SDK) for the TMF8828 has been developed to run on the NXP

LPC55S69-EVK.

SDK Source code examples include:

●Sensor calibration

●Simple configuration (9 zone distance reporting)

●Histogram output (9 zone configuration and 128bin reporting)

●Custom SPAD maps (reconfigure device to 4x4 mode)

LPC55S69 SDK download LINK

Please download the latest revision of the SDK, TMF882X_Driver_SDK_Source_vx.xx.zip from

ams.com and refer to TMF8828_Software_Development_Kit_Getting_Started_Guide.pdf for

installation and operations details.

3 Hardware Overview

The TMF882X-SHIELD board is an Arduino UNO form factor development platform for quick

evaluation of the TMF8820, TMF8821 & TMF8828 multi-zone dToF sensors.

Featuring a small sensor breakaway board, this EVM can be integrated into custom, prototype

hardware. The EVM includes an I2C level shifter and supply voltage regulator to allow the EVM to be

used with input voltages upto 5 V.

4 cover glass and air gap spacers are provided, to enabling evaluation of the optical performance.
