We’ve seen a bunch of IoT boards with 2G connectivity recently including Orange Pi 2G-IoT, Wio GPS, and Nadhat, but while in some countries 2G will still work for many years, those boards are already obsolete – or soon will be – in many other countries. However, finding low cost 3G / 4G boards is more difficult, and while one solution is to use 3G or 4G USB dongles, “OpenH – Open Hardware” – part of KLiP Industries – has designed two boards with 4G connectivity provided by Quectel modules. OpenH PULSAR Board PULSAR board is compatible with Arduino Zero and features the following specifications: MCU – Atmel/Microchip SAMD21 ARM Cortex M0+ MCU (the as the one used in Arduino Zero) Connectivity 4G LTE Cat M1 modem with GPS (Quectel BG96-NA); No external antennas required Bluetooth and NFC Security – Dedicated management CPU with crypto engine Power Supply 10W digital power supply and battery charger with direct solar input FCC […]
Quectel SC20 Smart LTE Modules with WiFi, BLE and GPS Run Android 5.1
Google may just have released Android Things operating systems for IoT applications, but its big brother – Android – has already gotten into some other IoT systems such as Quectel SC20 module powered by a Qualcomm processor and supporting LTE, WiFi, Bluetooth LE, and GNSS functions. Quectel SC20 comes in different flavors to cater for various markets, but all module share most of the same specifications: SoC – Unnamed Qualcomm processor System Memory – TBD Storage – 8GB flash Cellular Connectivity – FDD LTE, TDD LTE, TD-SCDMA, EVDO/DCMA, WCDMA, and GSM; antenna: MIMO 2×2, supports Rx-diversity Other Wireless Connectivity WiFi – 2.4GHz 802.11b/g/n (SC20-CE/-W); Dual band 802.11a/b/g/n/ac (SC20-E/-A/-AU/-J) Bluetooth 2.1+EDR/3.0/4.1 LE GNSS – GPS, GLONASS, and BeiDou Interfaces LCD – 4x lanes MIPI-DSI, 1.5Gbps each, HD (720p) @ 60fps Camera – MIPI-CSI, up to 1.5Gbps per lane, supports two cameras 2-lane MIPI_CSI for rear camera, up to 8MP 1-lane MIPI_CSI […]
