Reference designs are generic pdf files; Quickboards is production-ready. Use a library of modular blocks containing schematic, board layout, and firmware to quickly prototype your ideas.

[Quickboards @Quickboardsio]

Love the support we've seen for the library lately. We want to make sure Quickboards is building the exact blocks you actually need, so we're opening up a quick 6-question survey.

Take 60 seconds to help us shape the roadmap and get a 30% discount code for the full library as a thank you.

Tip of the day: Thermal vias

Exposed pads on QFNs aren't just for grounding—they’re heatsinks. Use stitched thermal vias to move heat to your ground plane and keep chips cool.

[Quickboards @Quickboardsio]

@crissgo1 Correct in that V+ should be connected to C12, but Josh beat you to it.

The LTC can handle 12 cells in series at 4.2V per cell, putting the V+ at 50V and has no issues, most other ICs would let off their magic smoke at that voltage though.

Check you DMs for a library discount!

SCHEMATIC CHALLENGE. WIN THE QUICKBOARDS LIBRARY (Schematic, firmware, PCB layout blocks + commercial rights)

The first person to identify the single critical design error in this schematic will win the Quickboards Library of production-ready, modular design blocks ($1,500 value).

Entrants must specify the rationale for the critical failure.

Rules: Strictly limited to one attempt per person. Accounts must be over 30 days old. Additional rules in the replies below. Noisy image to prevent AI from reading it.

Go.

@ShadowlessLabs The correct issue was that the V+ pin was not connected to C12, while the ISOMD should be connected to VREG (as pointed to in the datasheet) it still changes communication method to isoSPI when connected to 5V instead.

Thanks for participating, you've received something over DM.

@TirpitzTungsten We kept ramping up the noise floor until Gemini couldn't guess anymore. We'll try a better method next time.

[Quickboards @Quickboardsio]

@suarezvictor Correct, but Josh beat you to it. Thanks for participating, we sent something over DM.

[Quickboards @Quickboardsio]

@canary_earth Gemini came close to guess it, the noise helped confuse it.
While the values are not exact match for the datasheet, this circuit was tested and it works, the issue was the missing connection between V+ and C12.

Thanks for participating, we sent you something over DM!

[Quickboards @Quickboardsio]

@Josh12_z Congratulations to Josh for being the first to correctly identify the issue, you've won! We will send you the details over DM.

Datasheet friction, EOL redundancy, diluted innovation, revision risk, manual schematic capture risk and prohibitive evaluation costs are some of the traditional hardware R&D frictions.

Tip of the day: Calculate I2C Pullups

Stop defaulting to 10k for every bus. Calculate resistance based on bus capacitance; often 4.7k is the safer "all-rounder" for 400kHz+ speeds. You can also use our I2C Pull up resistor calculator: https://t.co/PhCU31unAm

@UboPod Funnily enough, that's how we started a year ago.

But there wasn't sufficient revenue to scale let alone pay our founder, and 99% of our customers only wanted the schematics-so we had to pivot.
