Just recieved the tps63900 breakout board.
Only took a few days for me in neighboring country.

Saves me a lot of time instead of developing it myself. Personally I might have used somewhat bigger config resistors and hand solder pads to play with current limiting perhaps?

Thanks for the “handwritten” personal note, much appreciated! Perhaps more valuable then the product itself nowadays.
And even received a present as well.
You’re too good for this world.

Very curious to beyonc the basic tests I’ve done so far!

HI Lodewijk,
thank you very much for taking the time to write this honest review 😊
I'm glad to hear you liked the board and the personal, hand-written note!

Haha, yes, I'm used to hand-soldering these tiny components (up to 0402), but others might find it difficult to do so. If I make another revision of this, I'll make it more tinker-friendly so it's not only easy to use, but also easy to modify 👍

Nice product

For High-efficiency lipo to 3.3V/5V converter

I received my parcel with an hand-written note inside from the Seller.
Many thanks for your thoughtfulness.
Product performances are really good.
Efficiency = 93% from 100µA to 100mA
Quiescent current (no load) = 433nA

Hi Xavier,
thank you very much for taking the time to write a review about the high-efficiency buck-boost converter. I'm glad to hear you liked the note!
Thank you for the detailed measurements as well! The specs seem to match the data-sheet in this case, although the IQ seems a bit higher than expected. I will look into the IQ again and update the description with your measured values once I can confirm the measured values

Best Regards,
AceInnoLab

As good as I hoped for!

For Inkycal - Create your own e-paper dashboard!

I love my InkyCal!
The product itself has both a handmade feel and yet is polished enough to sit on my shelf with no apologies!

There's some challenges presented by the backing services which I documented and wrote to Saad about. He was responsive for both his receipt of the issue and in providing a fix when the root cause was in his code.

If I ever do bring that idea of mine to Tindie, I hope that I can be as professional a developer and package my product as well as this!

Hi Raymond,
thank you very much for your honest review! I'm glad to hear you are happy with your Inkycal :D
Thank you for helping to find the minor bugs so they could be fixed right away. It's thanks to the great support from the community that Inkycal is where it is now.
I wish you good luck with your idea and look forward to seeing it on Tindie!

Highly recommended!

For Inkycal - Create your own e-paper dashboard!

It works (after adding the WFi creditals to SD-Card via computer) out of the box, configured by Web-UI. Very good communication with the seller, it's worth the price.
Thanks a lot.
