Power your Modules

There are several ways to energise your Hexabitz modules and arrays:

  1. Using coin cell battery holder modules (H04R1, H04R2): The output voltage is provided through Hexabitz SMD edge-pad connectors, which is 3.0V (in H04R1) and 3.3V (in H04R2) on the top and GND on bottom. You can solder multiple modules together to achieve more capacity. Note: H04R1 gives you 3.0V which might be not enough to run all the module functionalities. H04R2 generates a 3.3V through a linear regulator (LDO).
  2. Using USB-UART converter modules (H1AR1, H1AR2, H1AR3) connected to a computer USB port or a USB power bank. These three modules generate 3.3V on module power pads from the 5V USB source when closing the PWR jumper.
  3. Using USB-UART 3.3V prototype cable: You can use the USB-UART prototype cable to power your modules and to establish communication with them. Make sure that the cable VCC output is 3.3V! This Connection can be done either via 2-pin header connectors or Hexabitz BitzClamps.
  4. Using DC-DC power module (H03R0) with AC/DC wall adapter.
  5. Using DC-DC power module (H03R0) with a 9V battery.
  6. Using DC-DC power module (H03R0) with LiPo (lithium polymer)/LiFe (lithium iron phosphate) batteries – 2S (two series cells) or more. This is a good solution to get more current in a smaller size/weight.Lipo with array
  7. Using DC-DC power module (H03R0) with DC power supply or any other DC source > 5V.power supply with array
  8. Power your modules directly with single-cell LiPo/LiFo battery. A single LiPo/LiFo cell is usually between 3.5~4.2V. Thus, you will need to add a diode in series to get ~0.5V voltage drop and to keep the voltage level suitable for the MCUs. This configuration saves the cost and size of powering the module.
