About the BeeFASYER SPARROW PCB

BeeFASYER SPARROW is an open source ESP32 PCB design by beewarden, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 64.1 × 72.8 mm, with 121 components from 57 distinct parts.

Its main chip is the ESP32-C6-MINI-1/U, from the ESP32 family. Other key parts include the TPS25730DREFR, USBLC6-2SC6, TPS62903RPJR, BQ25798RQMR and MCP23017-E_SO. By type, the board carries 58 capacitors, 33 resistors, 7 connectors, 6 ICs, 5 transistors and 4 diodes.

It belongs with the iot & wireless, rf & radio and power & battery designs in this gallery.

From the project

Sparrow is the concentrator and gateway board for the BEEFASYER apiary-monitoring hardware platform. It collects data from Bluebird, Crane, and other compatible sensor boards, then forwards that data to the Beeforesight software platform over Wi-Fi or LTE-M using MQTT and ChirpSt

Sparrow is the concentrator and gateway board for the BEEFASYER apiary-monitoring hardware platform. It collects data from Bluebird, Crane, and other compatible sensor boards, then forwards that data to the Beeforesight software platform over Wi-Fi or LTE-M using MQTT and ChirpStack.

Each BEEFASYER monitoring network is centered on exactly one Sparrow.

The BEEFASYER hardware family consists of three main boards:
