The Simple HW detection was detecting the Pixhack V3 as a mini. This commit adds further discrimination, based on the fact the Pixhack V3 left VDD_5V_PERIPH_EN floating. Where a mini ,V2, V3 HW has it connected to the active low enable of the VDD_5V_PERIPH and VDD_5V_HIGHPOWER via a 10K pull down. The detection enables the 40K pull up and samples the pin. This reads back as a logical one on the Pixhack V3, and a logical zero on the Mini. Since the float is applied some 3.3 Ms post pin setting at reset the 10 us should leave the 5 Volt supplies in the on state because of the 10K pull down. This is assuming typical 40K pullup 10K pull down This results in typical 0.66V (.875V max) on the /EN pin which should not be detected as a high on the TPS2041.

PX4 Users
The PX4 User Guide explains how to assemble supported vehicles and fly drones with PX4. See the forum and chat if you need help!
PX4 Developers
This Developer Guide is for software developers who want to modify the flight stack and middleware (e.g. to add new flight modes), hardware integrators who want to support new flight controller boards and peripherals, and anyone who wants to get PX4 working on a new (unsupported) airframe/vehicle.
Developers should read the Guide for Contributions. See the forum and chat if you need help!
Weekly Dev Call
The PX4 Dev Team syncs up on a weekly dev call.
Note
The dev call is open to all interested developers (not just the core dev team). This is a great opportunity to meet the team and contribute to the ongoing development of the platform. It includes a QA session for newcomers. All regular calls are listed in the Dronecode calendar.
