Barley V-Flex

Barley V-Flex distills our proven Barley radar core into an ultra-versatile module for OEMs that need rock-solid Doppler speed detection, deep traffic analytics, and the freedom to adapt—all at a price that fits volume production. Powered by the ultralow-power MCU, V-Flex logs every vehicle in timestamped CSV or binary, speaks traffic protocols over TTL, USB, or 2.4 GHz radio, and jumps from sleep to full capture in microseconds—perfect for solar signs, battery counters, or cabinet-powered ITS nodes.

A new on-board MikroBUS™ slot joins the classic XBee™ socket, opening Barley V-Flex to 1,000+ Click™ add-ons: GNSS, LTE-M, LoRa, air-quality sensors, CAN-FD, PoE, and more—so you can prototype fresh ideas in minutes. Snap in LTE for cloud dashboards, GNSS for geo-tagged enforcement, or a BME680 to blend speed data with AQI—no re-spins, no hot-air gun, just plug-and-code with ready mikroSDK drivers. Coupled with its battery-backed RTC, field-upgradable firmware, and open ASCII command set, V-Flex is the Swiss-army radar engine for everything from entry-level speed signs to fully networked smart-city nodes.
