"The Electron is a tiny development kit for creating cellular-connected electronics projects and products. It comes with a SIM card and an affordable data plan for low-bandwidth things.
Imagine a cellular-connected Arduino, but with a more powerful processor and a SIM card. It also comes with Spark's development tools and cloud platform for managing and interacting with your new connected hardware."
Specs:
- STM32F205 ARM Cortex M3 microcontrollerData plan:
- 1MB Flash, 128K RAM
- Cellular modem: U-Blox SARA U-series (3G) or G-series (2G)
- 36 pins total: 28 GPIOs (D0-D13, A0-A13), plus TX/RX, 2 GNDs, VIN, VBAT, WKP, 3V3, RST
- Board dimensions: 2.0" x 0.8" x 0.3" (0.5" including headers)
"You don't need 4GB of data for a connected product, and you also don't need to spend $40/mo. We've negotiated global low-cost data plans for low-bandwidth products. Here's the story:
- $2.99/month for 1MB (approx. 20,000 messages per month)
- $0.99/each additional MB
- No contracts"
