Energy Harvesting Micro-M PCB
ADEH-MM-A
Features
Micro Module ADEH-MM-A is a small form factor energy harvester evaluation board targeting low power embedded applications where the main or auxiliary power requirements are fulfilled by means of thermoelectric generator(s) (TEGs) or a photovoltaic device. Low voltage (430mV) start-up capability enable harvesting operation from high impedance, low voltage ambient sources.
The evaluation board consists of two main blocks:
- Boost MPPT DC-DC converter
- Power meter with digital output
The ADEH-MM-A DC-DC output can be used for battery charging while the on-board LDO provides regulated voltage for low power microcontrollers or sensors. Additional benefit is the low standby current which is typically 10µA in shutdown mode.
Features
- Low voltage startup Vin = 250mV (5.0V max, Vin > Vout capable)
- Fixed output voltage Vout = 3.3V
- Auxiliary LDO output VLDO = 3.0V
- Power output –Pout MAX = 350mW (Vin=1.1V) / Pout LDO MAX=350mW (Vin=1.1V)
- On-board 30mF super capacitor maintaining Vout
- MPPT configuration resistors
- On –board digital power meter (I2C output)
- Breadboard compatible form factor (0.1” pitch)
- Edgeplated connections
- Additional through-hole for direct connection of TEG module wires
- Optional board to board connector on the bottom side (Plugs and receptacles available separately)
