MatchBox LoRaWan Gateway Review – Part 1: Unboxing and Teardown


Last spring, I wrote about MatchBox LoRaWAN gateway with GPS, WiFi, and Ethernet connectivity. The gateway is equipped based on a Mediatek WiFi module running Linux (OpenWrt/LEDE), Semtech chips for the LoRa part, and support up to 65,535 nodes, such as the as well as MatchStick, MatchModule, and MatchCore sensors provided by the company. I’ve just received MatchBox gateway for review, but I’m still waiting for 920-925MHz LoRa nodes as they are going through the FCC certification process, and I also have to wait for clarifications regarding local regulations. So in the meantime, I’ll check out the gateway hardware. MatchBox LoRaWAN Gateway Unboxing The gateway is shipped with a power supply, power cord, two antennas, an installation guide,… as well as three screws and pegs to wall mount the gateway and power supply, and in case you want to install the gateway on a pole, as shown below, for […]

This TTGO Board Combines ESP32, LoRa Radio, and OLED Display for just $10

Just one year ago, it would cost around $15 to $20+ to get an ESP32 board, that is if you were lucky/fast enough to order one one before it went out of stock. Since then, availability is no longer an issue, and you now can get an ESP32 development board for as low as about $7, or even around $4 during promotions. Today, I was made aware of another board sold under the “TTGO” brand, that includes not only ESP32 WiFi and Bluetooth SoC, but also a (433 MHz) LoRa radio, and an OLED display. Price? Just $10 plus shipping ($1.75 here). TTGO ESP32/LoRa board specifications: WiSoC – Espressif ESP32 Storage – 32MB on-board flash (or maybe just 16MB?) LoRa Semtech SX1278 with u.FL connector + 433MHz antenna (N.B.: Antenna must be connected during use or the Semtech chip could be damaged) Sensitivity” ~ -148dBm; output power: +20dBm Display – […]

WizziKit is a DASH7, LoRa and Sigfox Wireless Sensor & Actuator Network Kit

Over the last few years, I’ve written several article about LoRaWAN, Cellular IoT, and Sigfox based long range low power IoT solutions. DASH7 is another LPWAN (Low Power Wide Area Network) standard that operates on the same 868 and 915 MHz ISM bands as LoRa and Sigfox, but has much lower power consumption, and the cost of a shorter range up to 500 meters, instead of the 5+km associated with LoRa or SigFox. The DASH7 Alliance Protocol (D7A) is an Open Standard, and if you want more details you can download version 1.1 of the specifications on DASH7 Alliance website. I’m writing about DASH7 today thanks to an article on ST blog about Wizzilab’s Wizzikit, an evaluation kit and framework for DASH7 with a gateway, and several nodes that can also optionally support LoRaWAN and Sigfox protocols. The kit is comprised of the following items: WizziGate GW2120 Ethernet/Wifi/Dash7 gateway – based […]
