ES4L15BA1: World’s Smallest Bluetooth 6.0 IoT Module for Advanced Wireless Applications

As IoT devices get smaller and more advanced, there is a clear need for wireless modules that can support these innovations without adding complexity. The ES4L15BA1 answers this challenge with its world’s smallest form factor, making it a good choice for compact devices. It integrates Bluetooth 6.0 for reliable communication and enables precise distance measurement, enhancing its use in various applications.

The ES4L15BA1 uses the nRF54L15 chip from Nordic Semiconductor. This chip has an ARM Cortex-M33 processor running at 128MHz and a RISC-V co-processor for better performance. It includes 1.5MB of non-volatile memory and 256KB of RAM. For security, the module follows the PSA Certified Level 3 IoT security standard. It also meets FCC (Federal Communications Commission) and ISED (Innovation, Science, and Economic Development) certifications and is RoHS compliant.

As for wireless interfaces, the module supports Bluetooth 6.0 and other wireless technologies like 802.15.4, including Matter, Thread, and Zigbee. It offers different data rates: 2M, 1M, 500k, and 125kbps. The module works in a frequency range of 2402 to 2480 MHz with an output power of +8dBm. It needs a single power supply with a voltage range between 1.7V and 3.6V. Additionally, the module includes a PCB antenna, a 14-bit ADC, and a Global RTC. It can operate in temperatures from -40°C to 105°C.

ES4L15BA1: Applications

The compact design of the module, with dimensions of 3.25 x 8.55 x 1.00 mm, makes it useful in many areas. Its small size and wireless features make it suitable for PC accessories like wireless keyboards, mice, and other devices that need fast and energy-efficient connections. When included in gaming controllers, it can provide quick and smooth communication. This reduces delays and improves gameplay. The module also works in the emerging virtual reality (VR) and augmented reality (AR) devices, which need fast, low-power communication for immersive experiences. For smart home systems, the module can be used in devices like smart thermostats, lights, and security systems. It supports Matter, Thread, and Zigbee protocols. This makes it easier for devices to work together in different smart home setups.

The module supports the use of wearable health monitors and compact portable medical tools. These devices need a reliable wireless connection to send data. The module works across a wide temperature range and meets industry standards. This makes it useful for industrial IoT applications. In factories, it can help monitor machines, track assets, or predict when equipment needs maintenance. The module meets FCC, ISED, and RoHS standards, so it is approved for use in many industries and regions.

This product is still in development, expected to be released by February 2025. For more information, you can visit the official website.
