    • RE: Query regarding connecting bigger ESCs

      @Alex-Kushleyev Understood.

      We were thinking of the mini ESSC: https://www.modalai.com/products/voxl-esc-mini?variant=47206467371312. But that's not necessarily a hard requirement, is it written which ones have this jumper? Sorry if I missed it.

      We're not opposed to doing some of this ourselves either, if it's not a feature you were planning on or wanted to add. Before seeing this message we were brainstorming re-purposing the GNSS UART for this instead, and other such more "hacky" solutions.

    • Maximum I2C Clock Frequency

      Hi,

      As a followup to this, we've made an I2C driver for our magnetometer, which seems to work. Though reading X, Y, and Z values is taking a bit long for purposes (approx 2ms for all three at 400KHz I2C clock) given that we want to read from 4 of such sensors.

      We tried playing with a teensy microcontroller and found increasing the I2C rate to 1MHz clock worked well. Trying to increase the I2C clock speed in the voxl 2 mini we find that px4 crashes after loading the mag driver.

      I haven't been able to find anything online, but do you have information about the max i2c frequency for this device? We're repurposing the J19 MAG pins (bus 1) for this.
