This product is a Bluetooth module BLE 4.0 UART without adapter, low energy with serial transceiver.
Logic level conversion circuit. No external level of 5V is needed to become a 3.3V level.
The power input port is protected against the anti-circuit, to avoid the inverted accidental power plug, which leads to the module burn
HM-10, Bluetooth module HM-11 series using IT chip CC2540 / 2541, configuration 256Kb space, support
In commands.
You can change the paper (master and slave mode) and the baud rate, the device name, the pairing of the password and other parameters, convenient and flexible. BLE 4.0 UART Bluetooth Low Energy Module without Adapter features:
- Version AT-09 CC2541 Arduino Android IOS BLE
- Serial transceiver

The WIZ850io is a compact sized network module (Ethernet module) for Arduino and compatible boards based on the Wiznet W5500 chip, faster than the previous W5100.
