H13R00 / H13R10 Modules

H13R00 / H13R10 are compact coin-cell lithium battery holders that fit two CR2032 batteries in parallel (H13R00) or in series (H13R10). The output voltage is provided through Hexabitz SMD edge-pad connectors (3.0V in H13R00 and 3.3V in H13R10 on top and GND on bottom).

Note: This is a pre-release of our alpha modules. We have not started shipping hardware yet. We're staging some module pages online to share technical details and prepare for a beta launch this summer. You can pre-order modules here for free or chat with us if you have any questions or feedback!

Note: These modules do not ship with coin-cell batteries.

About Hexabitz

Hexabitz is a new kind of electronic prototyping platforms with game-changing modularity and a hint of biomimicry. Hexabitz modules connect with each other using a novel edge-soldering system and allow you to build tidy, compact and completely re-configurable electronic boards. Learn more about Hexabitz here.

Note: This is the first public offering of our alpha modules. We are still working on our website and production plans and hope to ship beta modules this summer. We have a very limited quantity of alpha modules available. We're excited to share some with makers who can't wait and want to build awesome things with Hexabitz. Your feedback and ideas are highly appreciated!

FAQ

Q: How much current do I get from a single H13R00?

A: Most CR2032 coin-cell batteries are about 200mAh capacity with a standard discharge current of 0.2mA. With two in parallel, you can get up to 450-500mAh of each H13R00 module.

Q: What happens if I have another higher voltage source in my board?

A: There is a reverse protection Schottky diode on H13R00 that prevents current from flowing back into the coin-cell battery in case you have higher voltage (e.g., 3.3V or 5V) applied at the same time. Note that although Schottky diodes have low forward voltage drop, the drop can reach 300mV at the above battery discharge rate. To avoid having a lower output voltage (3-0.3 = 2.7V), you can short the reverse protection diode on H13R00 with a solder jumper.

Q: How much current do I get from a single H13R10?

A: Most CR2032 coin-cell batteries are about 200mAh capacity with a standard discharge current of 0.2mA and voltage of 3V. With two in series, you can get same capacity but double the voltage. The voltage is regulated back down to 3.3V to be compatible with other Hexabitz modules. You can also solder H13R10 modules together, connecting them in parallel, to get more capacity.
