LoRa GPS tracker will soon even smaller as AcSiP has developed S76G and S78G systems-in-package (SiP) that combine LoRa, GPS and an MCU into a single 1.1 x 1.3cm package.
The two new modules are not listed on the company’s IoT-LoRa products page yet, but they appear to be an evolution of their S76S / S78S LoRa + MCU SiP released in 2016, so the new modules should have the following features:
- MCU – STMicro STM32L073x Arm Cortex M0+ MCU with up to 192 KB of Flash memory and 20 KB of RAM
- LoRa
- AcSiP S76G – Semtech SX1276 supporting global 868 MHz or 915 MHz ISM-Bands.
- AcSiP S78G – Semtech SX1278 supporting global 433 MHz or 470 MHz ISM-Bands
- GPS
- I/Os – I2C/SPI/UART/GPIO
- Package – 1.3 x 1.1 cm
The company will offers a complete SDK / HDK suite with latter likely similar to EK-S78S board pictured below but with an extra GPS antenna or connector.
