Particle E Series is a Family of 2G, 3G, 4G LTE Cellular IoT Modules Optimized for Mass Production

Cellular IoT has really taken off this year from the low cost Orange Pi 2G IoT board to 4G GPS Trackers, and global IoT SIM cards. Particle has been in this market for a couple of years, starting with their Electron boards, and the company has just announced the new Particle E series family of industrialized 2G, 3G, and LTE-enabled modules and a development kit. Key features of Particles E series modules: Cellular Connectivity u-blox SARA modules for cellular connectivity LTE: SARA-R410M 3G: SARA-U201/U260/U270 2G: SARA-G350 (2G) Embedded SIM card, Particle MVNO support in 100+ countries u.FL antenna connector MCU – STM32F205RGT6 120MHz ARM Cortex M3 microcontroller with 1MB flash, 128KB RAM Storage – • Expandable flash memory I/Os – 63-pin surface mountable castellated module with up 30x GPIOs, 12x ADC, 2x DAC, 13x PWM, 3x UART, 2x SPI, 1x I2S, 2x CAN, 1x USB 2.0 (Some signals are multiplexed) […]

The Future of Cellular IoT Explained – LTE M1, LTE NB-IoT, eSIM, and Battery Life Hype

Telecom companies also want their share of the IoT business, but with 2G to 4G cellular technology often being too power hungry and/or expensive for this market, 2G on-going – or upcoming – sunset depending on your location, LTE Cat M1 and LTE Cat NB1 (aka NB-IoT) standards have been developed, and used in products like Pycom FiPy board, and SARA-R4 and SARA-M2 modules. If you want to have an overview learn about the new LTE IoT standards and the future of cellular IoT, Particle has published a useful presentation – embedded below – dealing with both, as well as eSIM (Embedded SIM), 2G sunset, and battery life expectations. The main takeaways from my reading of the presentation: LTE NB1 is better suited for low power stationary sensors transmitting a small amount of data a few times a day. Requires new hardware and software LTE M1 can be used for […]
