About Lilypad Board:
The LilyPad for Arduino is a microcontroller board designed for wearables and e-textiles. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread.
NOTE: The board type of this Lilypad in the Arduino IDE is Arduino Mini w/ ATmega328.
Features:
- Can be directly programmed with the CH340G USB to TTL adapter module.
- Supports ISP download.
- Microcontroller: Atmel ATmega328P.
- Operating Voltage: 4.5 - 5.5V.
- Digital I/O Pins: 14 (of which 6 provide PWM output).
- Analog Input Pins: 8.
- Flash Memory: 32 KB of which 2 KB used by bootloader.
- SRAM: 2 KB.
- EEPROM: 1 KB.
- Clock Speed: 16 MHz.
- Uses: Smart car, smart home, Great for DIY projects

About the CH340G USB to TTL module:
This is USB to serial module that is based on the CH340G. It is commonly used to debug various TTL serial devices, upgrade the firmware of routers, and burn program onto Arduino Pro Mini, LilyPad Arduino directly.
