Most IoT devices either collects data via sensors or control other systems via various interfaces or both. Depending on the amount of data, serial, Bluetooth, WiFi, Ethernet or Lora long distance communication devices are available.

• WiFi client or server on a MCU. A Web Server or Web Client or both at the same time on a single IoT device.
• Data transfers via various web protocols, HTML headers, REST or FTP or custom interface to your back-end.
  
• 4G NB-IoT remote area data transfers, control and OTA updates.
• Bluetooth, Bluetooth LE connections to other devices.
• freeRTOS with LwIP, run multiple tasks on the same device at the same time. Monitor sensors while updating remote databases via REST or other protocols.
• Compress data to preserve bandwith before transmitting to host.
• Secure (encrypted) over the air (OTA) firmware upgrades, fully automated or manual browser based uploads. Batch or single device.
• Lots of sensors like capacitive touch sensors, hall sensors, temperature, humidity, barometric pressure, voltage, current, air quality and many more.
• SD Card interface, Ethernet interface as well as high-speed SPI, UART, I²S andI²C and Serial interfaces.
• Can Bus networks.
• 4-20mA industrial sensors.
• Displays like touch screens, e-paper  or LCD's of various sizes.
• RFID tags and readers for identification and access.
• Fingerprint readers for identification and access.
• Remote cameras with WiFi, Web Server, Web Client and FTP  capabilities.

Have a great IoT idea and not sure if it can work?

Let us design a prototype as well as do a CAD circuit board design ready for manufacturing.

How about easy cost effective prototyping?
