Web8 mrt. 2024 · Fortunately, the Raspberry Pi has an ‘overclocking’ setting in the boot file config.txt, which sets the clock rate to be used when the OS requests 50 MHz. This doesn’t just speed up the interface; a value of 1 or 2 MHz can be used to slow it right down, e.g. # Add to /boot/config.txt: dtparam=sdio_overclock=2. WebMost of these modules support several antennas (MIMO: Multiple Input Multiple Output) to increase data rates or to allow for the use of the Rx- and Tx-Diversity technologies.
