The Scoop provides backup power and facilitates reliable power management for Notecard-powered IoT applications. The Scoop includes a Lithium-Ion Capacitor (LIC), a hybrid type of capacitor classified as a type of supercapacitor. LICs have numerous advantages in comparison to using Lithium Polymer (LiPo) batteries as a power source as, in general, they are more reliable, have the ability to operate in a wider range of temperatures, experience a lower self-discharge rate, and are significantly safer to ship.
The Scoop includes a 250 Farads LIC, two JST connectors, and four pairs of header pins for flexible connectivity.
- Capacitor: Lithium-Ion 250F 3.8V. Provides reliable power and stable delivery over a short period of time.
- Connectors: JST Battery Connectors PH-2POS wired for Adafruit-style packs.
- Charge Connector: J1, Accepts 4.8V-24V.
- Output Connector: J2, Outputs 2.5V-3.8V.
- Header Pins: 4 pairs of through-hole mounted male header pins.
Internal testing resulted in the Scoop powering approximately 20 new cellular sessions with the Notecard, or up to 200 syncs between the Notecard and Notehub. Results may vary depending the type of wireless coverage in the area and the amount of data being sent.
The Scoop can be powered via its charge connector (
CHG), which accepts an
input voltage of 4.8V-24V, or via the adjacent header pins.
The output (
OUT) connector can deliver a voltage in the range of 2.5V-3.8V.
The Scoop was designed with a minimal footprint for easy embedding in existing applications.
- 59.69mm (2.35 inches) wide
- 20.0mm (0.79 inches) tall
- 14.16mm (0.56 inches) deep
The Scoop features four pairs of header pins, labeled as follows:
