Description

The MKL68BA-EU868 module is engineered for robust, long-range IoT connectivity. It combines the Semtech LLCC68 LoRa transceiver, which provides spread-spectrum modulation for excellent interference immunity and link budget, with the Nordic Semiconductor nRF52832 system-on-chip for Bluetooth Low Energy (BLE) 4.0 connectivity. This dual-radio architecture allows for flexible network topologies, where BLE can be used for local configuration and LoRaWAN for wide-area data backhaul.

Operating from a 1.75V to 3.6V DC supply, the module is optimized for battery-powered applications. Its industrial-grade operating temperature range of -40°C to +85°C ensures reliable performance in harsh environmental conditions. The inclusion of a U.FL connector allows for the attachment of an external, high-gain antenna to maximize the LoRa communication range.

Key Features

  • Dual-Radio Architecture: Combines LoRaWAN for long-range, low-power WAN connectivity with BLE 4.0 for short-range device configuration and data retrieval.
  • Extended LoRa Range: Capable of communication distances up to 7 kilometers in line-of-sight conditions with an appropriate external antenna.
  • Ultra-Low Power Design: Achieves a deep sleep current of 7 µA, significantly extending battery life in periodic transmission applications.
  • Industrial Temperature Tolerance: Rated for continuous operation from -40°C to +85°C, making it suitable for outdoor and industrial monitoring.
  • Regional Frequency Support: Primarily configured for EU868/IN865 bands, with variants available for other global LoRaWAN regions (US915, AU915, AS923).
  • High Power Output: Delivers up to 21 dBm (approx. 125 mW) of transmit power for maximizing link margin and range.
  • Compact Form Factor: Small 24mm x 19mm x 2.8mm PCB footprint enables integration into space-constrained devices and sensor nodes.

Applications

  • Smart Metering: Remote reading of water, gas, and electricity meters in urban and suburban LoRaWAN networks.
  • Agricultural IoT: Wireless monitoring of soil moisture, temperature, and other environmental parameters across large fields.
  • Asset Tracking: Low-power tracking of high-value assets in logistics, construction, and industrial yards.
  • Smart City Infrastructure: Monitoring street lighting, waste bin levels, and parking space occupancy.
  • Industrial Condition Monitoring: Wireless sensor nodes for predictive maintenance, monitoring vibration, temperature, or pressure on remote equipment.

Frequently Asked Questions

What is the primary power supply range for this LoRaWAN module?

The module operates from a wide supply voltage range of 1.75V to 3.6V DC. This makes it directly compatible with single-cell Li-ion/LiPo batteries (3.7V nominal) and regulated 3.3V system rails, which is ideal for battery-powered IoT sensor nodes.

How do I connect an antenna to the MKL68BA-EU868 module?

The module is equipped with a U.FL (IPEX) coaxial connector for the LoRa radio. You must solder a compatible U.FL pigtail cable to your PCB, which then connects to an external antenna. For optimal range, use a 5 dBi gain antenna tuned for the 868 MHz frequency band.

Can I use this module with Arduino or Raspberry Pi?

Yes, but it requires a host microcontroller. The module communicates via UART (serial AT commands) for LoRaWAN stack control and SPI for direct LLCC68 register access. You would need to interface its UART_TX, UART_RX, and other control pins (RESET, BOOT) to your Arduino or Raspberry Pi's GPIO, and develop or use existing firmware to manage the LoRaWAN protocol stack.

What is the difference between the sleep current and active transmit current?

The sleep current is extremely low at 7 microamperes (µA), which is the current drawn when the module is in its deepest power-saving mode. During active LoRa transmission at maximum power (21 dBm), the current draw can peak up to 115 milliamperes (mA). Proper power management is crucial to balance range and battery life.

Is this module certified for LoRaWAN operation in my region?

This specific variant (MKL68BA-EU868) is designed for the EU868 and IN865 frequency bands, covering Europe and India. For operation in other regions like North America (US915) or Australia (AU915), you would need to source the corresponding frequency-specific variant of the module, as radio regulations differ.
