Time for a two headed new Dragon , Seeed can make a drop in upgrade in Speed and Power efficiency just by swapping chips and minimal changes. WIN/WIN for everyone and seeed again leads the way in Innovation… Besides this year is the year of the Dragon. Let’s go !!!
trying to send me a message… LOL I’ll look them over.
here is sort of all that matters imo. But ZERO connectivity or serial only Deal breaker because a radio is a basic fundamental item in todays internet of things connected world. IMO.
Software Support: Compatible with C/C++ and MicroPython, ensuring easy project development and prototyping.
Rich Onboard Resources: Integrates an RGB LED, 2MB Flash, 520kB SRAM, and 19 multifunction GPIOs(Analog, Digital, I²C, UART, SPI, PWM).
Expanded 8 New IOs: Compared to previous XIAO MCUs, the addition of 8 IO pins on the back supports more complex applications.
Efficient Power Design: Ultra-low power consumption of just 27μA in sleep mode, enabling battery power supply. Direct battery voltage measurement via internal IO enhances the battery management system (BMS).

Working OT in my area.
Just got the latest in Development and prototype hardware bases from Nordic local rep as promised. Its a bargain for the DualCore nRF5340 development platform and the JLink alone. The thingy is more of a prototyping platform and contains many sensors. I’ll be introducing them and demonstrating some of the possibilities. With the next generation of Fresh hardware.
Coded PHY here we go!
Dual-Core Design: It features a 128 MHz Arm Cortex-M33 application processor and a 64 MHz Cortex-M33 network processor. This separation of application and network tasks can lead to more efficient processing and lower latency, particularly in complex applications.
Dedicated Network Processor: The network core is optimized for handling radio protocols like Bluetooth LE, ensuring that the application core is free for other tasks.
ESP32S3/C6:
ESP32S3: It has a single-core Xtensa LX7 processor, capable of running at up to 240 MHz. The dual-core architecture (found in the ESP32) is absent in the S3, which could lead to more contention between application and communication tasks.
ESP32C6: Features a RISC-V single-core processor and adds support for Wi-Fi 6, but again, lacks a dedicated core for networking tasks.

Angle of arrival and angle of departure
Bluetooth Direction Finding is based around the two key concepts of angle of arrival (AoA) and angle of departure (AoD). This makes use of the angular phase-shifts that occur between antennas as they receive (AoA) or transmit (AoD) RF signals.
With the use of antenna arrays at either side of the communication link phase shift data can be determined and from this, location can be calculated.
Seriously…
Bluetooth Direction Finding is the major feature of the Bluetooth 5.1 Core specification. It is designed to enhance location services where previously only signal strength based technology has been used with received signal strength indication (RSSI).
Bluetooth Direction Finding will offer new and improved use case for real time location systems (RTLS) for asset tracking in a wide range of scenarios from logistics and warehousing to value asset security in hospitals and factories. It also brings added user experiences in proximity-based scenarios for consumer awareness and contextual information.
Bluetooth Direction Finding can be used to detect location in either 2D or 3D dependent on the complexity of its implementation.
