TEC1-12715 12V Peltier Plate Module (1B5 Peltier 12V 40x40)

Description: Thermoelectric coolers (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity.

This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side will heat quickly, the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or other block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortably cold we could not hold our finger to it.

Note: It is imperative that a heat sink is used on the hot side of the module. Running the module without one can cause damage to this part. If it’s too hot to comfortably touch, you’re in the danger zone!

Raspberry Pi Compute Module 3 (AW Compute 3)

The Raspberry Pi Compute Module 3 (CM3) is a DDR2-SODIMM-mechanically-compatible System on Module (SoMs) containing the same processor, memory, and supporting power circuitry as the Raspberry Pi 3.

These modules allow designers to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition the modules have extra IO interfaces over and above what is available on the Raspberry Pi boards, providing more options for the designer. The Raspberry Compute Modules 3 are suitable for designers who are happy with Raspberry Pi 3 functionality but require a smaller form factor (67.6 mm x 31 mm) for their embedded designs.

Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2837 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the Module into a custom system should be relatively straightforward as all the tricky bits are pre-built into the module.

The Compute Module 3 Lite contains the following components contained within a 200 pin SODIMM design:

  • Broadcom BCM2837 Processor (1.2GHz)
  • 1GB LPDDR2 RAM
  • 35u Hard Gold Plated IO Pins
  • DDR2-SODIMM, Mechanically-Compatible System on Modules (SoMs)
  • 4 GB eMMC Flash memory. Also these modules have extra input/output (I/O) interfaces in addition to the Raspberry Pi model A/B boards.
  • 67.6mm x 31mm Board
