The Bluetooth module wants 3.3v logic levels so that is taken into account. The image above shows a buffer chip doing the conversion, but the Fritzing schematic on the post uses a voltage divider.

Bluetooth is what your Mac uses to connect to wireless devices like keyboards, mice, trackpads, speakers, and other peripherals. Generally, it's ...

The main components of the upgrade kit are a BM62 Bluetooth module that connects to a modern phone, a PIC18F27Q43 microcontroller to implement the car phone’s interface and menus, and several ...

Bluetooth 3.0 + HS, as it'll be called, promises to be markedly faster than prior iterations thanks to the reliance on 802.11, which is the same protocol used by WiFi modules, routers, etc.

Raspberry Pi has introduced the Radio Module 2, a small but powerful wireless module priced at just $4.This module is aimed at makers, developers, and organizations using RP2040 or RP2350 ...

Murata has collaborated with Cypress Semiconductor to create Type 1LV, a low-power Wi-Fi and Bluetooth module occupying 10 x 7.2 x 1.4mm. “When comparing Type 1LV to the {earlier] Type 1DX,” according ...

Both modules are ideal for WLAN and Bluetooth connections, delivering lightning-fast data rates of up to 1201Mbps.

The modules are the FC30R, a cost-effective, industrial-grade Wi-Fi module; the FCU743R, featuring Wi-Fi 4 and Bluetooth 5.2 capabilities; and the FCM740D, an MCU with Wi-Fi 4 and Bluetooth 5.2.
