Wio LTE GPS Tracker Board Comes with a 4G Modem, Supports Espruino Firmware (JavaScript Programming)

Seeed Studio launched Wio GPS tracker with a 2G GSM module a few months ago, and while it should work in some countries, others are phasing out 2G networks, and only support 3G or 4G. The company has now launched an update with Wio LTE board with the same form factor, and most of the same features except they replaced the 2G/Bluetooth/GNSS module with a 4G LTE/GNSS module, and Atmel SAMD21 ARM Cortex M0+ microcontroller by an STMicro STM32 ARM Cortex-M4F MCU. Wio LTE board specifications: MCU – STMicro STM32F405RG ARM Cortex M4F MCU @ 168 MHz with 1MB flash, 192+4KB SRAM Storage – micro SD slot Connectivity via Quectel EC21-A (America) module LTE Cat.1 modem: FDD LTE: B2/B4/B12 WCDMA: B2/B4/B5 AT Command: 3GPP TS27.007 and enhanced AT Commands Data – LTE-FDD Max 10Mbps(DL) Max 5Mbps (UL) NanoSIM card 2x u.FL antenna connectors GNSS – GPS/BeiDou/GLONASS/Galileo/QZSS with 1x u.FL GNSS […]

OpenH PULSAR and QUASAR Boards Add 4G LTE Cat M1, or Cat 4/1 to Raspberry Pi Boards

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 […]
