CBC-EVAL-09 EnerChip EP Universal EH Eval Kit
Note that during the time the S2 push button is depressed no power is passed from the EVAL--09 to the target
load. The following table provides a quick reference of the LED indicators and their meaning.

Suggested Energy Harvesting Transducers
Thermoelectric Generators (TEGs)
- There are several vendors of thermoelectric generators. MicroPelt
model MPG-D651 or MPG-D671 have been verified with the CBC-EVAL-09. MicroPelt’s evaluation system is TE-
Power PLUS, described on www.micropelt.com and available at Mouser. Nextreme also supplies a small TEG,
model eTEG HV56 Power Generator. Contact Nextreme directly at www.nextreme.com.
Piezo Electric Generator
- There are several vendors of piezoelectric generators. Mide piezo units V20W,
V25W, V21B, V21BL, V22B, and V22BL have been verified with the CBC-EVAL-09. Mide’s website is www.mide.
com. Another vendor is Advanced Cerametrics (ACI). Model numbers PFCB-W14, PFCB-W24, and PFCB-W54
will work with the EVAL-09. ACI’s website is www.advancedcerametrics.com.
Alternate Energy Harvesting Generators
- New solutions for harvesting ambient energy are emerging
from companies and universities worldwide. Please contact Cymbet Applications Engineering to discuss your
requirements.
Connecting EVAL-09 to Other Vendors’ Radio and Microcontroller Boards
Connectors J9 and J10 are designed to be connected to various microcontroller and radio boards from any
of several vendors. For proper operation in energy harvesting environments, it is often necessary to load
special firmware into the vendor’s target board. For information on downloading proper firmware for the Texas
Instruments eZ430-RF2500 target board, see Cymbet application note AN-1040: EVAL Kit GUI and TI ez430-
RF2500 Firmware Readme, located on the Cymbet website at http://www.cymbet.com/pdfs/AN-1040.pdf.
