PB-03 – A Bluetooth LE 5.2 module for the Smart Home, wearables, IoT, etc… (Sponsored)

What changes does Bluetooth LE 5.2 (BLE 5.2) bring? Maybe PB-03 module can tell you.

PB-03 is a BLE module developed by Shenzhen Ai-Thinker Technology based on PHY+ PHY6252 32-bit microcontroller (see PDF datasheet) that offers high integration and low power consumption down to 0.3uA in OFF mode, and is well suited to various applications such as IoT, mobile devices, wearable electronic devices, and smart homes.

PB-03 module’s highlights

Ai-Thinker PB-03 provides an upgrade to earlier PB-01/02 modules with the following highlights:

  • MCU – PHY6252 microcontroller with 256KB flash, 64KB SRAM
  • Supports BLE 5.2 and Bluetooth Mesh
  • Equipped with an on-board PCB antenna
  • Up to 2 Mbps data rate
  • I/Os – UART, PWM, ADC, I2C, SPI, PDM, DMA, and up to 19 IOs.
  • Security – AES-128 encryption hardware
  • Power consumption (PHY6252)
    • 0.3uA @ OFF Mode (IO wake up only)
    • 1uA @ Sleep Mode with 32KHz RTC
    • 3.5uA @ Sleep Mode with 32KHz RTC and all SRAM retention
    • Receive mode: 8mA @3.3V power supply
    • Transmit mode: 8.6mA (0dBm output power) @3.3V power supply
    • MCU – <90uA/MHz
  • Small size –  2.6 x 1.82 x 0.3 cm (SMD-52 package)

Ai-Thinker provides software to support BLE Mesh, Tmall Genie smart speaker,  as well as Amazon Alexa platform.

PB-03 applications & use cases

PB-03 can meet the power consumption requirements of most application scenarios, as the RF output power is adjustable, and other features can be fine-tuned. As such, the Bluetooth LE 5.2 module provides an optimal balance between the communication range, data rate, and power consumption.

I can’t understand which ISA is used by the MCU. It’s not mentionned in the pdf linked. Is that something new ? I doubt, but if so, then there’s a huge need for documentation, toolchain, and so on.

The information about the ISA is not provided, but I doubt it’s something new.

Just thought the same. Why don’t they say it? It’s weird. I don’t know. Doesn’t look very professional.
