As a starting point let's consider the ESP32-CAM Board with WiFi, Bluetooth, and OV2640 Camera Module - 2 Pack, a dual-mode development board that utilizes PCB on-board antennas and cores based on ESP32 chips.
This tiny module integrates WiFi traditional Bluetooth, and BLE Beacon, making it an all-in-one solution for developers.

One of the crucial features of the ESP32-CAM board is its low-power dual-core 32-bit CPU for application processors which can deliver up to 240MHz and up to 600 DMIPS. Additionally, it comes with built-in 520 KB SRAM and external 4M PSRAM, making it perfect for applications that require extensive memory usage. The board also supports various interfaces such as UART/SPI/I2C/PWM/ADC/DAC, making it versatile and easy to integrate into existing systems.

The most significant advantage of the ESP32-CAM board is its ultra-small 802.11b/g/n Wi-Fi + BT/BLE SoC module which packs a punch despite its tiny size. One potential disadvantage is that it may require a bit of tinkering to get it up and running if you're not familiar with development boards. However, the plethora of online resources can guide you through the process and make it a breeze.

Without a doubt if you're in the market for a powerful yet compact development board that can handle various interfaces and has built-in WiFi and Bluetooth capabilities, the ESP32-CAM Board with WiFi, Bluetooth, and OV2640 Camera Module - 2 Pack is an excellent choice. Its versatility and compact size make it ideal for numerous applications from home automation to robotics. Overall, this tiny yet powerful board delivers on its promises and is worth the investment.
