Raspberry Pi based ModBerry series with 3G/LTE modem support

Nowadays, mobile Internet offers are becoming more and more popular. They are often cost-effective for those who do not download too much from the web. Usually you don’t even need to sign a contract – some operators offer fairly favorable pre-paid internet offers. Anyway, even if we want an Internet contract, sometimes the monthly fee is lower if we do not take the device.

In that case, how will we receive this Internet? The solution is simple – unfortunately we have to invest some money in the LTE modem. As a router separating the signal we will use Raspberry Pi. For a ready and complete solution we can choose ModBerry Industrial IoT devices already equipped with modem of our choosing

ModBerry M500 modem configurability

ModBerry M500 added wide range of I/Os to the board, including RS232/485 serial ports, digital and analog I/Os, 10/100Mbps Ethernet port, USB, 1-Wire and optional CAN. ModBerry series also offers additional wired interfaces and wireless communication modules with their proprietary modules called ExCard. The range of wireless modules include 3G/LTE, NarrowBand-IoT (NB-IoT), Wireless M-Bus, ZigBee, LoRa, Sigfox, Wi-Fi, Bluetooth and many more.

Kimχ Micro SBC (Raspberry Pi Zero size) with Quad-Core Processor

A new alternative for the Raspberry Pi was presented. The Raspberry Pi Zero Micro SBC called Kimχ Micro has a quad-core processor and an mPCIe slot for adding PCIe cards.

Kimχ Micro includes the NXP i.MX 8M Mini processor with up to 4 ARM Cortex-A53 cores. These cores can be clocked up to 1.8 GHz and are complemented by the ARM Cortex-M4F real-time core and the Vivante GC NanoUltra 3D graphics processor. The latter allows Kimχ Micro to encode and decode 1080p content at 60 FPS.

In addition, Kimχ Micro SBC contains 1 GB of LPDDR4 RAM, 8 GB of eMMC flash memory and a Micro SD card reader. There is also a serial EEPROM. Kimχ Micro also has a built-in mPCIe connection for adding PCIe cards, such as Wi-Fi cards. By the way, the board must support LTE or LoRA cards.

Kimχ Micro (preliminary) specifications:

  • SoC – NXP i.MX 8M Mini single to quad-core Cortex-A53 processor @ up to 1.8 GHz, Cortex-M4F real-time core @ up to 400 MHz, Vivante GC NanoUltra 3D GPU + GC320 2D GPU, VPU for 1080p60 video decoding and encoding; (Single and dual-core version of NXP i.MX 8M Mini processor are also compatible)
  • System Memory – 2GB LPDDR4
  • Storage – 8GB eMMC flash, MicroSD card socket, serial EEPROM
  • USB – 1x USB 2.0 Type-C port for power and data
  • ExpansionmPCIe socket for wireless cards (e.g. WIFi, 4G LTE, or LoRa).
  • Sparkfun Qwiic header
  • 2x 60-pin high-density I/O headers with Ethernet, USB, camera, display, SAI audio, I2C, SPI, GPIO, PCIe, etc…
  • Debugging – 10-pin JTAG header footprint, Cortex-M4 UART “M4” header, Cortex-A53 “Console” header
  • Misc – Power button, button 1 (boot selection) and button 2 (user button), R, G, and B LEDs
  • Power SupplyUSB PD via USB-C port, NX20P3483UKUSB PD and Type-C high-voltage sink/source combo switch and PTN5110NHQZ TCPC compliant USB Power Delivery (PD) PHY IC
  • 5V unpopulated header
  • 2-pin header for 1S LiPo Battery; on-board PMIC, charging, fuel gauge, and battery protection ICs
  • Dimensions – 65 x 32 mm (FYR – Raspberry Pi Zero: 65 x 30 mm)

Industrial use of Raspberry Pi and Raspberry Pi-like boards

A year ago, TECHBASE released an updated version of the ModBerry M500 industrial IoT computer, replacing the aging Raspberry Pi 3 with a 3B+, giving it better performance. With the recent launch of the Raspberry Pi 4, TECHBASE has yet again, announced another upgrade to the M500, which now packs the latest single-board computer.

Over 10 million Raspberry Pi’s have been sold and the Raspberry Pi is likely to stay as a new standard in the industry. Official Raspbian OS is free operating system based on Linux Debian optimized for the Raspberry Pi comes with over 35,000 packages, pre-compiled software bundled in a nice format for easy installation. ModBerry devices are compatible with Raspberry Pi accessories, supported by Raspberry Pi Foundation. ModBerry M500 now with Raspberry Pi 3 Model B+ / Raspberry Pi 4 Model B support.
