FTDI 232 Basic 3.3V 5V USB to TTL CMM Programmer Adapter, 6Pin Module for Arduino
This FTDI programming tool can be used with our Ardu32 game console or Bare Bones Arduino kit to
program over serial using the Arduino IDE.
It features a selectable 5V and 3.3V logic selector on the bottom. Simply cut the trace between the center
pad and 5V and solder up the center pad to the 3.3V pad to convert from 5V TTL to 3.3V TTL.
The programmer features an Arduino compatible DTR data line to automate the reset process, eliminating
the need to press reset right when programming is to take place.

Dual 16340 Rechargeable Lithium Charge Board, 5V Micro USB Power Supply Module
The mobile power is stacked on the Arduino board and powered via the 5V/GND pin. We also provide a USB-A output
interface that you can use to connect to other devices using a USB cable. The charging interface is micro USB, and the
charging tool is very convenient to obtain (such as: Android mobile phone adapter). When it is stopped, it is recommended
to turn off the power output and let the mobile power supply enter the standby state, thus saving limited battery energy.
