General Description AXO-EVB3 evaluation board is intended to easily and quickly perform characterizations of AXO215 accelerometers. AXO-EVB3 was specially designed to be interfaced with an Arduino M0 or Arduino Yn boards. The combination of AXO-EVB3 with the Arduino platform is ideally suited for tests with rate table over the temperature range -40C to +85C . The 1.8V, 3.3V and 5V compatibility for SPI communication also enables connecting the AXO-EVB3 with most of the acquisition systems and microcontrollers in the market. This document describes the mechanical and electrical features of the AXO-EVB3 board as well as the SPI protocol used for the digital communication. This document is applicable to the whole AXO product line, including AXO215 accelerometers. For more information about performances of each product, please refer to the dedicated datasheet, available on our website. Infernal ref. : MCD009-B Copyright 2018 Tronics Microsystems S.A..
