The UVLO is here
You might remember that part of the power control strategy is to use a UVLO (under voltage lock-out). Well, here it is. It’s a simple […]
power source
back to Afro ESC (for 22V operations) + feedback frequency
The basic Afro ESC doesn’t support enough voltage for my needs (the solar panel can deliver as much as 22V). I tried the Spider ESC, […]
Need for a UVLO
I gave a first shot at prototyping with a teensy, R78 for power regulation, an Attopilot voltage + current sensor and an Olimex LCD display, […]
First smooth working of both UARTs simultaneously and external power circuit
I got the modem + GPS + USB logging working smoothly. I’m stepping away from ChibiOs for now, because I can get something working well […]
satellite modem – MCU communication problem solved
I started by replacing the modem with a trusty GPS, so I have a continuous flow of data with a checksum (GPS lines are checksumed) […]
