ExRockets Blog | SMALL FLIGHT COMPUTER (BREO N)

This small flight computer is the same computer as my MINI FLIGHT COMPUTER (BREO M) but it has two more powerful MOSFET transistors instead of the small ones I used on BREO M and the mounting holes are 4 at the corners instead of 2 in the middle which makes it much easier to solder and to install in the rocket. In order to fit the two larger D-PACK MOSFETs I had to increase the width with 5 mm so the new dimensions are 60x20x15 mm. Nevertheless, BREO N still  has the same excellent functionality as BREO M.  The main characteristics are: – Barometric altitude measurement up to 18km – High g acceleration sensor – 40 samples per second / 13 bit ADC – 3.5 minutes recording time – Igniters connectivity check for both channels (LEDs for each channel will show the status of the igniter) – USB connection – 7.5 to 16 VDC power supply with on-board ON-OFF switch – 10A (40A pulse) MOSFET for each channel – Selectable on-time for each channel (between 0.1 and 5 seconds) – Each channel has igniter connectivity feedback… //  Дальше — www.blog.exrockets.com
