(การลงโมดูล esp12e esp12f บน pcb adapter board และ วาง ldo Regulator XC6206P 5v to 3.3 พร้อมกับ flash โดยร่วมใช้งานกับ witty cloud power supply board )
Assemble parts together and flashing fw. Esp8266-12e,12f + PCB ADAPTER +
XC6206P332PR 3.3v Regulator
-รวมชุด esp8266-12e,12f เข้ากับ pcb adaptor (กรณี Vcc=5v ติดตั้ง ldo regulator แปลงเป็น 3.3v) สุดท้ายจะทำการ flash firmware ด้วย
-flash ด้วย
1. ft232rl (usb to ttl) สำหรับ Vcc 3.3v (กรณี esp ไม่มี ldo regulator) และ 5v( esp82266 ที่มี ldo regulator)
2. witty cloud mini nodemcu ใช้ power supply board ของ witty cloud มาใช้ flash firmware ให้กับ esp82266 ที่มี ldo regulator
This clip is about:
-How to flash esp8266 firmware.
-How to flash esp8266 12e.
-Assemble part together an Esp8266 module , PCB ADAPTER and XC6206P332PR Regulator.
-Flash with usng ft232rl(for Vcc of esp 3.3v /5v).
-Flash with Witty Cloud power supply board(for Vcc of esp 5v).
Note. This adapter but not soldered or any additional wires for pin CH_PD ,GPIO15 if you want.
This adapter existed
1. CH_PD is pulled to Vcc by 10k resistor (so module start working after You provide Vcc).
2. GPIO15 is pulled down to GND by 10k resistor.
So to burn new flash image just connect GPIO0 to GND during start.

TOREX XC6206P332PR Fixed LDO Voltage Regulator, 1.8V to 6V, 250mV Dropout, 3.3Vout, 200mAout,
SOT-89-3
The XC6206P332PR (linear ,low dropout-regulator) is a 3-terminal highly precise low power consumption
Positive Voltage Regulator manufactured using CMOS and laser trimming technologies. The XC6206 series
provides large currents with a significantly small dropout voltage. The XC6206 consists of a current limiter circuit, a
driver transistor, a precision reference voltage and an error correction circuit. The series is compatible with low ESR
ceramic capacitors. The current limiter's foldback circuit operates as a short circuit protection as well as the output
current limiter for the output pin. Output voltages are internally by laser trimming technologies. It is selectable in 0.1V increments within a range of 1.2 to 5.0V.

PCB ADAPTER FOR ESP8266 MODULES
Adapter is for ESP8266 -07 and -12. Version Modules -07 and -12 are in format not ready to plug in breadboard. When You solder module onto this adapter You plug it directly into breadboard or use standard F-M wires to get access to all GPIO on board.
Adapter has pin CH_PD pulled up to Vcc, so after You supply Vcc, ESP starts without any additional wires.
This adapter makes working with ESP8266 much easier. CH_PD is pulled to Vcc by 10k resistor (so module start
working after You provide Vcc). GPIO15 is pulled down to GND by 10k resistor, so to burn new flash image just
connect GPIO0 to GND during start.
Wrong silkscreen on adapter/module
Depending on production batch some -07 and -12 modules have replaced GPIO4 and GPIO5. Before You solder in
ESP module check if silkscreen on adapter is correct to avoid errors later. You can take picture of bottom side of
ESP module (there are GPIOs described).
