6.67-inch flexible AMOLED display works with Raspberry Pi, LattePanda, and other SBCs with HDMI output

DFRobot has introduced a 6.67-inch flexible AMOLED display with a 2400×1080 resolution, designed for easy use with single-board computers such as Raspberry Pi and LattePanda. While flexible displays are common in smartphones, they are difficult to interface with SBCs, so DFRobot added a dedicated MIPI-to-HDMI driver board for plug-and-play compatibility with a wider range of platforms. The panel is just 1.2mm thick and bendable, enabling curved and space-constrained designs, while delivering 450 cd/m² brightness and 16.7 million colors. Like typical OLEDs, it offers deep blacks and high contrast without requiring a backlight, making it suitable for applications ranging from wearables and robotics to industrial HMI systems. DFRobot 6.67'' flexible AMOLED Display specifications: Compatibility – Raspberry Pi, Banana Pi, Orange Pi, and most devices with an HDMI output. Display Panel Screen Size - 6.67 inches Screen Material – Flexible AMOLED Resolution – 2400 x 1080 (SPR - Sub-Pixel Rendering) Aspect Ratio

RainbowLink-V2 compact USB-to-serial converter features 12V output, dual TTL, isolated RS-485 and RS-232 interfaces

DFRobot's RainbowLink-V2 USB-to-serial converter features four independent channels, namely one isolated RS-485, one isolated RS-232, and two TTL interfaces usable simultaneously. The compact tool also converts 5V provided from the host's USB interface to 12V/800mA, 5V/2A, and 3.3V/200mA outputs, eliminating the need for a separate power adapter. RainbowLink-V2 (TEL0190) specifications: USB - 1x USB Type-C port for power and adata Serial 2x TTL (3.3V) via headers 1x fully isolated RS485 channel via lever terminal 1x fully isolated RS232 channel via lever terminal Baud Rate - 2400 to 128000 bps Misc 3x Power LEDs for 3.3V, 5V, and 12V 4x Link LEDs for TTL 1/2, RS232, and RS485 12AWG - 22AWG wires supported on lever-type spring terminals Built-in short-circuit protection and overcurrent protection (but users are still recommended to avoid short-circuiting to prevent damage) Input voltage - 5V via USB-C port Output voltage 3.3V up to 200mA via header 5V up

DFRobot launches low-power, low-cost Fermion: BMV080 air quality sensor module

Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost alternative, the Fermion: BMV080, which provides the same fanless, laboratory-grade PM1, PM2.5, and PM10 sensing capabilities for just $29.90. The sensor uses laser-based light-scattering technology with fanless optical counting to detect particles as small as 0.5 μm. This avoids fan noise, dust buildup, and mechanical wear, which are common with fan-based PM sensors, and, on top of that, it has a service life of up to 10 years. It measures particulate concentrations in a 0–1000 μg/m³ range with 1 μg/m³ resolution and ±10 μg/m³ of accuracy. The sensor supports I2C and SPI interfaces, and consumes about 70 mA in continuous measurement mode with a 6 μA sleep current, making it suitable for battery-powered systems.

DIN-rail mountable LoRaWAN control terminal offers RS485, analog input, and digital I/Os

The DFRobot LoRaWAN Control Terminal is a compact, DIN-rail mountable industrial IIoT terminal that features long-range LoRaWAN connectivity with local sensing and control capabilities. It’s designed for industrial, agricultural, and building-automation scenarios that need reliable, low-power wireless communication up to 4 km. The terminal supports the standard LoRaWAN protocol (OTAA/ABP, Class A/C) with up to 4 km line-of-sight range and works with private gateways or public networks like TTN. It integrates a 0–10V analog input, optically isolated digital inputs, and RS485/Modbus sensor support, along with a built-in relay output for direct actuation. There's also support for visual rule-based automation for relay switching, RS-485 commands, or uplink messages; the device continues operating offline using preset logic. The unit operates from 12–24V, includes adjustable transmission parameters, and supports firmware upgrades and factory resets. DFRobot LoRaWAN Control Terminal specifications: SoC/Main Controller – TBD Wireless LoRaWAN 863–870 MHz, 16 dBm Tx power (EU, DFR1120-868) LoRaWAN
