PowerBridge Developer Kit
This energy harvesting developer kit combines Energous’ radio frequency (RF) solution
with e-peas’ power management IC technology to support at-a-distance wireless power
applications for smart buildings, industrial IoT sensors, retail electronic displays and more.
Applications
• Smart Buildings
– Temperature/humidity
occupancy sensors
– Window/door sensors
• Industrial IoT
– ESL for warehouse operations
– Air quality/CO2 monitor
– Cold storage chain monitoring
• Retail Electronic Displays
– ESL for retail shelving
– ESL for cold storage
– Smart shopping carts
The 1W WattUp® PowerBridge transmitter
incorporates the EN4100 and EN3210
devices. The EN4100 is a highly integrated
System-on-Chip (SoC) RF transmitter IC,
while the EN3210 is a 1W, high-efficiency
power amplifier (PA).
On the receiver side, there are 3 input paths
available to choose from based on use case,
including discrete diode and EN2223 RF-to-
DC implementations, which connect to the
AEM30940 ambient energy manager chip.
