| | | Firms Team for Low Power IoT Person Detection |
| Maxim Integrated has announced that its MAX78000 neural-network microcontroller detects people in an image using Aizip’s Visual Wake Words (VWW) model at just 0.7mJ of energy per inference. This is 100 times lower than conventional software solutions, and the most economical and efficient IoT person-detection solution available, says Maxim. The low-power network provides longer operation for battery-powered IoT systems that require human-presence detection, including building energy management and smart security cameras. |

| | | Rugged Transport Computer Features LTE, Wi-Fi, GPS and Optional LoRa |
| Eurotech announced a multi-service IoT gateway for rolling stock, automotive, heavy duty vehicles and rugged industrial applications. The LTE CAT1-equipped BoltGate 10-12 follows earlier BoltGate models including the smaller, Apollo Lake based BoltGate 20-31. It has the same 1GHz, Cortex-A8 TI Sitara AM335x SoC as the company’s DynaGate 10-12. |

| | | Mini-PCIe Adapter Enables M.2-based 5G |
| Gateworks offers a variety of mini-PCIe modules for its Arm/Linux SBCs, including last year’s Sub-1GHz and BLE-equipped GW16122 IoT Radio. Now, to keep its customers up to date with the latest M.2-form factor 5G cellular modems, the company has launched a 5G Cellular M.2 Adapter that supports modem modules up to 52mm in length. The adapter is a mini-PCIe card for Gatework's Ventana, Venice, and Newport SBCs equipped with an M.2 B-key slot that supports 5G modems plus dual nano-SIM slots. |

| | | Special Feature: Technology Innovation Propels 5G Forward |
| As 5G systems deploy worldwide, a variety of devices are adapting to accommodate the requirements and challenges of the technology. 5G-ready solutions—in the form of antennas, amplifiers, network accelerators and more—are paving the way. Circuit Cellar's Editor-in-Chief, Jeff Child, looks at the key technology and product trends associated with 5G. |

| | | U-blox LTE-M, NB-IoT Module Gains 400MHz Support |
| U‑blox has extended its SARA-R5 LTE-M and NB-IoT communications family with the introduction of a module that supports the 400-450MHz LTE spectrum bands available in Europe, Asia and Latin America. The U-blox SARA-R540S can communicate on LTE bands 31, 72, 73, 87 and 88. These lower-frequency bands have good propagation characteristics, helping customers in the smart meter, public safety, smart grid and smart cities markets meet strict indoor and outdoor coverage requirements. |
|
| Pi-sized SBCs Run Linux on RK3328 and Allwinner H3 SmartBoardHome has announced two 85mm x 56mm SBCs that run Linux: a “Pi-R2S3328-B” with an RK3328 and dual GbE ports and a “Pi-PC-H3 PK” with an Allwinner H3, HDMI, CSI, LAN, 2x USB, Wi-Fi and 40-pin GPIO. |
