This is a TTGO T8 V1.7 ESP32 8MB PSRAM TF CARD 3D ANTENNA WiFi &amp, Bluetooth ESP32-WROVER-Unsoldered. The module is used in the radio frequency range. This module has a powerful enough onboard processing and storage capability that allows it to be integrated with other application-specific devices through minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, which is designed to occupy a minimal PCB area. It is also used in Bluetooth.

Features:

1. Lastest ESP32 Version: REV1
2. WIFI & Bluetooth
3. 4MB Flash & 8MB PSRAM
4. Lithium battery interface, 500mA Max charging current

Package Includes:

1 x Unsoldered TTGO T8 V1.7 ESP32 8MB PSRAM TF CARD 3D ANTENNA WiFi & Bluetooth ESP32-WROVER Micropython 16MB FLASH

The Beetle Ble (Former name as Bluno Beetle)  is a board based on Arduino Uno with Bluetooth 4.0 (BLE).  It is probably the smallest BLE board in the market.  It uses standard Arduino IDE to upload codes via without any extra library and drivers.  This Beetle BLE is another milestone in the Beetle line, which makes DIY users have more options in the project design. It is fully compatible with Bluno in instructions and procedures. Support Bluetooth HID and ibeacon modes. You may also check the Bluetooth microcontroller selection guide to get more information.

The Beetle BLE is a super tiny and low-cost Arduino-compatible board with Bluetooth 4.0. The Beetle BLE can be used for disposable projects, such as DIY projects, workshops, gift projects, E-Textiles wearable, and educational. For students and makers who can not afford too much on hardware purchasing, Beetle can be a great solution.

Just like a native Arduino board, but with Bluetooth 4.0. An APP called Play Bluno is available on IOS and Android which gives quick access to this little tiny board.
It not only supports USB programming but also wireless uploading method. With the V-shaped gilded I/O interface, it is convenient to screw conductor wire on it, which could a good choice in the wearable market.
