Seeeduino Lotus Cortex-M0+ is an ATMEGA SAM D21 Microcontroller development board. The Atmel® | SMART™ SAM D21 is a series of low-power microcontrollers using the 32-bit ARM® Cortex®-M0+ processor with 256KB Flash and 32KB of SRAM. you can consider the Seeeduino Lotus Cortex-M0+ as a combination of Seeeduino and Base Shield. 

Seeeduino Lotus Cortex-M0+ has 14 digital input/outputs (10 of which support PWM) and 6 analog input/outputs, 3 Serial Communication Interface, a micro USB connector, a JST2.0 Li-Po connector, an ICSP header, 12 Grove connectors, a reset button.  

Seeeduino Lotus Cortex-M0+ is an upgraded version of Seeeduino Lotus V1.1, it replaces a more powerful chip, optimizes the circuit layout, and the power supply is more stable. Because this chip supports direct USB level output, there is no need to use a serial port to USB chip, like CP2102N. Therefore, one more hardware serial port is available to the user.   

Features

      • Compatible with Arduino UNO
      • ARM® Cortex®-M0+ 32bit 48MHz microcontroller(SAMD21)
      • 12 on-board Grove connectors
      • 14 Digital I/O Pins (10 PWM outputs)
      •  6 Analog Inputs
      • Support Power Path Management
      • Support micro-usb or Li-Po battery powered
      • 2A maximum charging current
      • Suitable for low power design

  • The Seeeduino Lotus Cortex-M0+ SKU 102010228 Seeduino Lotus Cortex-M0+ has a SDW lable. What is this connection set used for?
    Question by: Alex Bruski on 2019-02-27 20:16:11

    Hi Alex, Sorry, do you mean SWD? I do'n found the SDW lable. If you mean SWD, it's a interface for burn the firmware. Regards

  • Can I connect a solar panel for charging? What input voltage range?
    Question by: Matt on 2019-02-27 19:17:14

    Hi Matt, yes, you can use the solar panel for power supply. You can find the input votage range in the Learn Tab -- wiki. It's 3.5V to 4.2V. And please pay attention that, if you use a solar panel to charge this board, do not plug the micro-USB at the same time. Otherwise,the usb port will charge the solar panel, it may damage your solar pannel.

    Answer by: admin on 2019-02-28 10:44:01

    If you need to use the solar panel, you need to use DC-DC module to conver the input voltage to 3.3V before you plug it into the JST2.0 port. The Vsys can not over 4,4V.
