  • 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!

  • Just a quick note that the current consumption value of ~35 mA noted in "Features" is incorrect. According to the ZED-F9P data sheet, the current draw can range from approximately 68 mA (GPS + tracking) to 130 mA (GPS+GLO+GAL+BDS + acquisition).

  • Given the impressive quiescent draw the Artemis can achieve (2.5 μA), it would be great to see the next revision of this board have jumpers for the LEDs, microphone and the MCP73831 charger.

  • Really happy to see Paul Clark's design manufactured as a SparkX product! I picked up a couple of these guys and have really enjoyed working with them. Complete control over power and communications using only a Qwiic cable. No more Molex connectors to worry about. When placed in low power mode, the Qwiic Iridium 9603N only draws 1 uA (0.001 mA)!

    Also, a quick note to potential users that you can purchase an Iridium 9603N directly from Rock Seven for $135 USD instead of having to pay $249 USD for a RockBLOCK 9603 only to cannibalize the transceiver.

  • Yup! It sure can.

    The Qwiic Micro was added to the SparkFun SAMD board definitions a few days ago, which appear to be available in the Arduino IDE Boards Manager (v1.7.0).

  • Just ordered this board and am looking forward to working with it! I'm curious though, why weren't mounting holes included in the design? They would have really come in handy for QWIIC-based or other projects that don't involve soldering.

  • Thanks for the detailed reply, Nate! I picked up the board from Digi-Key and can't wait to start testing!

    Also, super cool beehive project! :)

  • It's really great to see SparkFun leading the development of boards with the new u-blox modules!

    However, I'm curious to know the reasons behind only including a u.FL connector. Given the available real-estate, it appears the board could have accommodated the pads for an edge-launch SMA connector. This would have had the benefit of providing users with the option for a more direct and reliable antenna connection. I know I constantly worry about the fragile u.FL cables/connectors.

No public wish lists :(
