New KSGER Soldering Station – Featuring Hengshuo MCU

[forrest96er]

Hey everyone,

I just wanted to share that KSGER has released a new soldering station powered by a Chinese MCU, the CX32L003F8 from Hengshuo.

This new model increases the maximum temperature to 500°C and raises the power limit to 120W.

Has anyone else picked up this station? Could it be supported by this project?
From what I can tell, the seller appears to be the official KSGER store.

I haven't worked with Hengshuo MCUs before, so I can't say much about the development environment or tools available for it.

If you're interested in buying this station or modifying an existing KSGER unit, here are some links:

Hi, this MCU is extremely small and there's no way this fw could fit in it

Key Differences:

1. Performance:

   • The STM32F103C8T6 runs at 72 MHz with a Cortex-M3 core, making it much faster.
   • The CX32L003F8 runs at 32 MHz with a Cortex-M0+, designed for power efficiency.

2. Memory:

   • Both have 64 KB Flash, but the STM32F103 has 20 KB RAM, while the CX32L003F8 has 4 KB RAM.

3. Peripheral Support:

   • STM32F103C8T6 has more advanced peripherals, including USB 2.0, CAN, multiple UARTs, and more timers.
   • CX32L003F8 lacks USB and CAN but has basic peripherals suitable for simpler applications.

4. Power Consumption:

   • The CX32L003F8 is designed for ultra-low power consumption, making it better for battery-operated applications.
   • The STM32F103C8T6 consumes more power but offers higher performance.

5. Voltage Range:

   • The CX32L003F8 supports a wider voltage range (2.5V - 5.5V), making it easier to use in 5V systems.
   • The STM32F103C8T6 operates at 2.0V - 3.6V, requiring level shifting for 5V logic.

Which One Should You Choose?

• Choose STM32F103C8T6 if you need high performance, USB, more peripherals, and faster processing.
• Choose CX32L003F8 if you need ultra-low power, a wider voltage range, and a cost-effective low-power MCU.
