GPS
- GPS Satellite Positioning Module NEO7M UBLOX Satellite Positioning 51 SCM STM32
- Specifications:
- Working Voltage: 3.3v-5.0v
- Color: As Picture Shown
- Description:
- With micro USB interface, you can debug GPS module with ordinary phone data cable, no longer need to use USB-TTL and other tools.
- TTL interface is reserved to facilitate the use of USB-TTL or external microcontroller to control and receive GPS information.
- Ceramic antenna on module board, no GPS external antenna can be used to search for stars.
- Reserved SMA antenna interface, can use external antenna, star search ability is stronger.
OLED Display
Description
- OLED display, no need backlight, self-illumination.
- The display performance is better than the traditional LCD display, also lower consumption.
Specifications
