Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing 7. Support the Ar duino development environment Parameter: WiFi: 802.11 b/g/n, up to 150Mbps Bluetooth: Bluetooth LE, Bluetooth 5, Bluetooth mesh Hardware Resource: 7*ADC1+2*ADC2; 7*Touch; 3*UART; 2*I2C; 2*SPI, etc. Memory: 384KB ROM; 512KB SRAM; 16KB RTC SRAM; 8MB SiP Flash Interface: Type-C USB; 2*1.25 lithium battery interface; 2*18*2.54 Header Pin Battery: 3.7V lithium battery power supply and charging Power consumption: Deep sleep 10 uA Operating temperature: -20~70℃ Dimensions: 50.2 * 25.5* 10.2 mm Package Content: 1 * Power Cord 1 * ESP32 Development Board 2 * Pin Headers Review: Great for led projects - Simple to use with arduino and fastled, has a ton of memory to run those big projects Review: Arrived with bottom corner of OLED broken. - Update: Issue promptly handled by Seller - I give this 3 stars because when I unpacked it and set it up to test, I noticed that the bottom left corner of the OLED was broken off. I powered it on anyway to see if it worked. It partially worked ... the sample code was displaying text but it was missing lines. I assumed that I had handled it carelessly and wrote it off and ordered another. It arrived in one day (the other arrived in 2). When I removed it from the packaging (with much care this time), it ALSO had the bottom left corner broken off. It powered up OK but same sketchy display. While I like this format (OLED on WiFi board), I think it needs better shipping packaging, so two stars knocked off. I also ordered the LoRa version (x2) and they arrived undamaged and worked great. (All 4 devices were in an anti-static bag that was in a small yellow shipping envelope.The OLED doesn't have any support on the two bottom corners ... easy to get broken.) UPDATE: Seller has taken care of these broken devices and has indicated that the shipping packaging is changing, I REALLY like this ESP32 and OLED format so I have added back the 2 stars. Great customer focus and concern. ## Features - [Full documentation]: English documentation: https://robotzero.one/heltec-wifi-kit-32/; https://docs.heltec.cn/#/en/user_manual/the_upgrade_of_new_wifi_kit_32; Install guide and bunches of info: https://github.com/HelTecAutomation/Heltec_ESP32; Instructable for Internet Time: https://www.instructables.com/id/WiFi-Kit-32-NTP-Clock/ Driver Library - u8g2: https://github.com/olikraus/u8g2 - [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); - 6.

New WiFi Kit 32 schematic diagram: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/blob/master/SchematicDiagram/New_WIFI_Kit_32_Schematic_diagram.pdf; 8. Circuit optimization, system more stable; 9. Better power manage system design. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076KJZ5QM | | Best Sellers Rank | #85,728 in Computers ( See Top 100 in Computers ) #1,295 in Single-Board Computers | | Brand | MakerFocus | | Built-In Media | 1 * ESP32 Development Board, 1 * Power Cord, 2 * Pin Headers | | CPU Model | Tegra | | CPU model | Tegra | | CPU speed | 2.4 GHz | | Compatible Devices | Personal Computer, Arduino, OLED Display | | Connectivity Technology | USB, Wi-Fi | | Customer Reviews | 4.2 out of 5 stars 300 Reviews | | Installed RAM memory size | 8 MB | | Item Dimensions L x W x H | 5L x 2.5W x 0.1H centimeters | | Item Weight | 5 g | | Manufacturer | MakerFocus | | Memory Storage Capacity | 8 MB | | Memory storage capacity | 8 MB | | Mfr Part Number | UZM173505AEVXI378 | | Model Name | WiFi Kit 32 (V3) | | Model Number | 8541612336 | | Model name | WiFi Kit 32 (V3) | | Operating System | Arduino | | Processor Brand | Espressif | | Processor Count | 1 | | Processor Speed | 2.4 GHz | | RAM Memory Installed | 8 MB | | RAM Memory Technology | LPDDR | | Total Usb Ports | 1 | | UPC | 190033879688 | | Wireless Compability | 802.11abg | ## Product Details - **Brand:** MakerFocus - **CPU model:** Tegra - **Installed RAM memory size:** 8 MB - **Memory storage capacity:** 8 MB - **Model name:** WiFi Kit 32 (V3) ## Images ![ESP32 Development Board WiFi with 0.96inch OLED Display WIFI Kit32 Arduino Compatible CP2012 for Arduino Nodemcu - Image 1](https://m.media-amazon.com/images/I/71rrXAYHrOL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for led projects *by A***M on 6 June 2023* Simple to use with arduino and fastled, has a ton of memory to run those big projects ### ⭐⭐⭐⭐⭐ Arrived with bottom corner of OLED broken. - Update: Issue promptly handled by Seller *by D***L on 21 February 2018* I give this 3 stars because when I unpacked it and set it up to test, I noticed that the bottom left corner of the OLED was broken off.
