  • Can anyone provide comment as to whether the supply voltage influences the sensitivity of the receiver?

  • What's the difference between the new FreeSOC board and the old one? I didn't see any comparision in the product pages other than "a new version is available."

  • This is perfect! Any chance a similar (all in one with no supporting components) step-up is on the way? Preferably one that comes with adjustable or varying outputs.

  • Thanks for the transparency! I'm no web developer but I figured it'd be a fairly involved change. Good to know it's at least on the radar.

  • Do you guys have any plans on adding configuration options to your product pages? For most instances it's not necessary but for products with multiple different configuration (e.g. the Actobotics motors which have tons of different speed/torque configurations) it'd be nice to have a dropdown to select the configuration rather than different product pages for each one. That way reviews and comments could be collated together.

  • Is there a way to charge the series multiple charger/booster configuration without disconnecting them? I assume the grounds aren't isolated on the board so you'd have to either provide 10V split between the two USB ports or charge from two isolated 5V outputs, right?

  • I'm seeing an issue where the processor falls back into interpreter mode when I connect something to pin 12. After looking at the schematic it looks like this is an MTDI pin which has some special startup purpose? Is there anything I can do to allow me to use this pin?

  • The Espressif CEO mentioned in a Facebook post (https://www.facebook.com/groups/1499045113679103/permalink/1731855033731442/?hc_location=ufi) that the ESP32 and ESP8266 have 5v tolerant GPIO. Can you confirm that this is the case on the ESP32 Thing and a 5V input won't fry anything?

  • I was trying to hack together an Alexa skill for my robotic vacuum project the other week, but this makes things much clearer. Thanks!

  • It seems implied by the video and description that these can be set up to make large banks of parallel batteries, however the comments from the other, standard Li-Ion batteries (the JST ones) suggest that they should not be placed in parallel unless the cells are carefully balanced. What sets these tabbed batteries apart from the JST ones in this regard?
