- [Note]: This ESP32 development board comes unassembled, soldering of headers is required. It can lithium battery powered, the lithium battery is not included, battery may be purchased here: https://www.desertcart.com/dp/B07CXNQ3ZR; Add battery power detection circuit. Use ADC2_4 (GPIO 13) to read battery voltage. Please refer to this example: https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/examples/ESP32/ADC_Read_Voltage/Battery_power/Battery_power.ino
- [This is an upgraded version WiFi Kit 32! ] What's the Upgrade of New WiFi Kit 32? 1. 4MB (32M-bits) FLASH upgrade to 8MB (64M-bits) FLASH; 2. Better 2.4GHz antenna design and impendence matching; 3. Basic low power design (800uA in deep sleep); 4. Add battery power detection circuit. Use ADC2_4 (GPIO 13) to read battery voltage. Please refer to this example: https://github.com/HelTecAutomation/Heltec_ESP32/blob/master/examples/ESP32/ADC_Read_Voltage/Battery_power/Battery_power.ino;
- 5. Add Vext power output pin, users can use this pin to drive some external device (sensor, motor etc.), when system need into deep sleep mode, Vext can be turn off. This pin was controlled by GPIO21, for example: Turn ON: digitalWrite(21, LOW); Turn OFF: digitalWrite(21, HIGH);

## Questions & Answers

**Q: How do i connect to arduino ide?  i can't figure it out from the referenced web site**
A: This Heltec board differs somewhat from other ESP32 boards with an OLED display I have used.  For example, programs that work with the Wemos Lolin32, I've had to edit the display() constructor as follows:  "SSD1306 display(0x3c, 4, 15):".  Also you must reset the OLED display in setup() with the following code:    "pinMode(16,OUTPUT); digitalWrite(16, LOW); delay(50); digitalWrite(16, HIGH);".  You can see an example of this in the file "Heltec-Aaron-Lee/WiFi_Kit_series/esp32/libraries/OLED/examples/SSD1306SimpleDemo/SSD1306SimpleDemo.ino" on github.com.

**Q: Does the display use i2c or other?**
A: It uses I2C. CLOCK = 15, DATA = 4, RESET = 16

If you are using the U8G2 library, the line you want for software rendering is 

"U8G2_SSD1306_128X64_NONAME_F_SW_I2C g_OLED(U8G2_R2, CLOCK, DATA, RESET)"

For hardware rendering, the order of the pins changes 

"U8G2_SSD1306_128X64_NONAME_F_HW_I2C g_OLED(U8G2_R2, RESET, CLOCK, DATA)"

**Q: Is this preflashed?  some heltec esps will boot when powered via usb outa the box, this doesn't seem to.**
A: Mine did but I reflashed it right away with my own program

**Q: Is there a breakout board with terminal blocks this fits in? Doesn't seem to fit those made for devkit c.**
A: I think I just plugged ribbon header cables into it to test.
