Workbench essentials
Workbench essentials is the honest name for this drawer: Peltier coolers, heatsinks, heating elements, laser optics, LilyPad LEDs, conductive thread, and parts that don't fit anywhere else.
Peltier TEC modules, heatsinks for Raspberry Pi and Jetson boards, PTC heaters, laser diodes, LilyPad sewable LEDs, conductive stainless thread, nOOds LED filaments, and thermal paper rolls.
- Thermal control spans both directions: Peltier TEC modules (3.75V–12V, 1A–5A) and PTC heating elements (5V, 40°C and 100°C setpoints) for active cooling and warming without a compressor or resistance wire.
- Heatsinks for Raspberry Pi 4/5/Zero, Jetson Nano, Jetson Xavier NX, LattePanda Mu, and ROCK Pi 4SE — passive and fan-assisted options, with thermal pads included on the Pi 5 variant.
- E-textile supplies: LilyPad sewable LEDs in multiple colors and sizes, conductive stainless thread (2–60 Ω/yard), conductive thread ribbon cable, and conductive material packs.
- Optics, consumables, and BOSON modules: 650nm 5mW laser diode, KY-008 laser transmitter, laser mirror, nOOds flexible LED filaments (12V and 24V), 57×50mm thermal paper rolls, and Counting/Duration/Threshold/LED BOSON modules.

Swap guidanceCan I swap these?
Pick the board you have - we'll show what we know about swapping it.
Known swap options (1)
General board checks (5)
- Name the job first: building a circuit, adding an indicator, driving addressable RGB, measuring temperature, controlling a motor, switching a load, keeping time or adding storage.
- Match the required interface: solder pads, header gender, analog voltage, single-wire RGB data, SPI, USB, GPIO or motor coil outputs.
- Check voltage, current, heat, connector pitch, breadboard fit, required resistors, firmware library and whether the board needs a separate controller.
- Do not swap a passive part for an active module, or a module for a bare component, just because the package looks similar.
- Use the linked product page or guide for final pinout, ratings and library details before buying.
