The IO Expander Board is based on the Microchip MCP23017 Expander Chip. This high-performance IC, allows connection to a range of High-Speed I²C buses, including the standard 100kHz bus, as well as the newer 400kHz and 1.7MHz bus standards. 

ORDER CODE: RDL637

The board has only one SSR driven by TTL circuit . The board works on 12V but the input signal can come directly from microcontroller output working at 5V to control SSR. Each SSR can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of SSR is indicated by LED.

Industrial IoT Gateway for Real-Time BLE Data Collection

The BLE Gateway is an industrial IoT device designed to collect data from Bluetooth Low Energy (BLE) devices such as asset tags, sensors, and wearables, and securely transmit the data to cloud platforms or local servers.

The gateway acts as a bridge between BLE devices and enterprise IoT infrastructure, enabling real-time monitoring, analytics, and asset visibility across factories, warehouses, hospitals, and smart buildings.

Using Bluetooth Low Energy, the gateway can detect multiple BLE devices simultaneously and forward the data through Ethernet, WiFi, or cellular connectivity.

 ORDER CODE : RDL867

MC14049UBDR2G Logic, Buffer, MC14049, 3 V to 18 V, SOIC-16

The MC14049UB hex inverter/buffer is constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. This complementary MOS device finds primary use where low power dissipation and/or high noise immunity is desired. This device provides logic−level conversion using only one supply voltage, VDD. The input−signal high level (VIH) can exceed the VDD supply voltage for logic−level conversions. Two TTL/DTL Loads can be driven when the device is used as CMOS−to−TTL/DTL converters (VDD = 5.0 V, VOL ≤ 0.4 V, IOL ≥ 3.2 mA). Note that pins 13 and 16 are not connected internally on this device; consequently, connections to these terminals will not affect circuit operation.
