Micro Module ADEH-MM-B

Description

Energy Harvesting Micro Module

The Energy Harvesting Micro Module 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-B DC-DC output provides regulated voltage for low power microcontrollers or sensors while the on-board charger controller can be used for battery charging. Additional benefit is the low standby current which is typically 1uA in shutdown mode.

Features

• Low voltage startup V_in=430mV (5.0V max, V_in > V_out capable)
• Fixed output voltage V_out=3.0V
• Auxiliary Battery Charger output V_BATT=3.1V
• Power output – P_{out MAX}=500mW (V_in=2.5V)
• On-board 47uF storage capacitor maintaining V_out
• MPPT configuration resistors (default: solar)
• 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
