The AsteRx-m2 Development Kit is specifically designed to simplify the development
process for new integrations.
3.1 Header Types
All headers have a pitch of 2.54mm, with the exception of J500 (PPS/EVENTS) and J501
(GP). Those headers have a 2mm pitch.
3.2 Powering the DevKit
There are two ways to power the DevKit:
1. From the USB Dev connector (J205). This allows powering the board from a PC or
from a standard phone-charger adapter. The supported USB voltage range is 4.5V-
5.5V.
2. Using the POWER connector (J203). The supported voltage range is 5-36V.
When powering from the USB Dev connector, it is recommended to use the USB cable
provided with the DevKit. Low-quality USB cables often suffer from excessive voltage
drop, preventing correct operation.
