  • Super cute! Is there a 5V big brother with the AP63205 in the works?

  • I think these carrier boards are a great concept! I'm curious why 0.1" breakout pins for SDA/SCL weren't included?

  • Would be great to get a PWR LED jumper on this board!

  • Are there any power consumption figures for the nRF52840 (e.g. transmit, sleep, etc.)? Would be helpful for potential users to have them listed on the "Features" tab.

  • I'm currently using the Qwiic Power Switch as a solution for reducing the sleep current of several power-hungry Qwiic devices, including the 9DoF IMU Breakout - ICM-20948, and GPS Breakout - ZOE-M8Q. It's working great! A single line of code to turn the devices ON/OFF makes power management simple as pie.

    I should note that the quiescent draw actually appears to be 77 µA when a load is connected (as opposed to the stated 0.2 µA), but compared to the tens of milliamps the u-blox GNSS receiver typically draws, it's a happy compromise.

    Would be great to see this SparkX product go red!

  • I'm super excited about the release of the MicroMod Data Logging Carrier Board.

    Users should be aware that the 10kΩ/20kΩ voltage divider is tied directly to VIN and will draw up to 200 uA at 6 V. As there is no jumper pad to disable the voltage divider (yet), it'll be necessary to break out an X-acto knife to cut the trace or a hot air rework station to desolder the SMD resistor(s) to reduce the quiescent draw.

  • Woah, didn't see this coming! Super exciting!

    I agree with JordenLuke that a terminal block MicroMod board would be super awesome!

  • Great to see this board with an SMA connector! I've been constantly worrying about damaging the u.Fl connector on the GPS-RTK2 board over the past several months.

    It's important to note that the power consumption value of ~35 mA is not correct.

    The actual power consumption, as listed in the ZED-F9P datasheet, ranges between 68-130 mA. Both the GPS-RTK2 and GPS-RTK-SMA product pages should be updated to reflect this.

  • What a beast! Looking forward to working with the OpenLog Artemis!

    Now if you'll excuse me, I'll be holding a funeral for my Qwiic OpenLog.

  • Psst! You guys forgot the mounting holes!

    In all seriousness though, I understand that you're trying to fit as much functionality into a 1" square as you can and that sacrifices must be made, but I was really left scratching my head. The RV-8803 deviates from the standard Qwiic design by not having at least two mounting holes, so standoffs can't be used. On the backside, it can't be soldered to a protoboard with 0.1" headers because of the CR1225 battery holder. On the topside, the Qwiic connectors also prevent using 0.1" headers. Are the only options right-angle 0.1" headers and 8-pin female headers? Please correct me if I'm wrong!

    Mounting aside, I'm super excited to see a low-power temperature-compensated RTC hit the streets! I've been waiting for a DS3231SN replacement for over 3 years!

No public wish lists :(
