Discover the Homefixer ESP8266 devboard, a unique development board for the ESP8266-12F. It's incredibly user - friendly, eliminating the need for extra hardware like programmers and voltage regulators. With a wide - range switching regulator, you can power it using various battery types, from a single AA cell to LiPo cells. There's even a USB charger on the board for LiPo cells. The ADC is connected to the battery via a voltage divider, which you can turn off to save power when not in use. This board is compact yet packed with features and is breadboard - compatible. Key features include ultra - low power optimization, being one of the smallest ESP8266 devboards, zero - power battery voltage measurement, easy access to most pins, auto - reset support for firmware upload, LiPo charging from USB, wide supply voltage range, exposed setting pins for TSP61201, pre - wired deep sleep, and breadboard compatibility. Specifications include an ESP8266 - 12F, micro - usb for power and code upload, a battery voltage range of 0.8 - 5.5V or USB power, a TPS61201 3.3V boost converter, a LiPo charge current of 500mA (adjustable), an ADC with 0 - 5V range, and a size of 27 x 24 mm. The package includes one Homefixer ESP8266 devboard. Check the project page (wiki link) for more details.
Using the Homefixer ESP8266 devboard is a breeze. First, decide on your power source. You can use a single AA cell, multiple LiPo cells, or simply connect it via the micro - USB. If you're using LiPo cells, the built - in USB charger will keep them topped up. To upload firmware, the CP2104 usb to uart with auto - reset support will automatically get the board into bootload mode. When measuring battery voltage, you can take advantage of the voltage divider feature. If you don't need it, turn it off to save power. For deep sleep mode, just connect the pre - wired solder jumper. When it comes to maintenance, keep the board clean and dry. Avoid exposing it to extreme temperatures. If you need to adjust the LiPo charge current, you can do so by changing the resistor. And always refer to the project page (wiki link) for any further questions or more in - depth information.
