CobraV2

Overview

reciever_module - folder with code for reciver which will send data to the pc sender_module - folder with code for sender, which transmit data to the reciever and save it on the micro sd card serial_read - read serial input and save it

Modules

10 DOF IMU

SDA (Serial Data)
SCL (Serial Clock)
INT (Interrupt) is a digital interrupt output
FSYNC is a frame sync signal

L76K GPS

PPS (Pulse per second) powers a led wich will blink and indicate that GPS is working
RX (UART communication)
TX (UART communication)

NRF24L01+

CE (Chip Enable) is an active-high pin. When enabled, the nRF24L01 will either transmit or receive, depending on the mode.
CSN (Chip Select Not) is an active-low pin that is typically held HIGH. When this pin goes low, the nRF24L01 begins listening for data on its SPI port and processes it accordingly.
SCK (Serial Clock) accepts clock pulses from the SPI bus master.
MOSI (Master Out Slave In) is the SPI input for the nRF24L01.
MISO (Master In Slave Out) is the SPI output of the nRF24L01.
IRQ is an interrupt pin that can notify the master when there is new data to process.
