This ESP32 based WEMOS Lolin32 Lite compatible WiFi enabled Development Board comes with MicroPython Firmware (Interpreter) installed. All you need to program it, is a USB or serial (RX/TX) connection to the host (computer) and a terminal program. Programming is a lot simpler than Arduino (based on C), and can be done without the need for a special development environment (like Arduino IDE or AVR Studio).

Power Supply: 2.2V to 3.6V
Logic Level: 3.3V
– Xtensa 32-bit LX6 core, operating at 160 or 240 MHz and performing at up to 600 DMIPS
– Ultra low power (ULP) co-processor
– 520kB SRAM
– 4MB Flash
Wireless connectivity:
– Wi-Fi: 802.11 b/g/n
– Bluetooth: v4.2 BR/EDR and BLE Peripheral interfaces*:
– 12-bit SAR ADC up to 18 channels
– 2 8-bit DACs
– 10 touch sensors (capacitive sensing GPIOs)
– Temperature sensor
– 4 SPI
– 2 IS interfaces
– 2 IC interfaces
– 3 UART
– SD/SDIO/CE-ATA/MMC/eMMC host controller
– SDIO/SPI slave controller
– Ethernet MAC interface with dedicated DMA and IEEE 1588 Precision Time Protocol support
– CAN bus 2.0
– Infrared remote controller (TX/RX, up to 8 channels)
– Motor PWM
– LED PWM (up to 16 channels)
– Hall effect sensor
– Ultra low power analog pre-amplifier
– IEEE 802.11 standard security features all supported, including WFA, WPA/WPA2 and WAPI
– Secure boot
– Flash encryption
– 1024-bit OTP, up to 768-bit for customers
– Cryptographic hardware acceleration: AES, SHA-2, RSA, elliptic curve cryptography (ECC), random number generator (RNG)
Power management:
– Internal low-dropout regulator
– Individual power domain for RTC
– 5uA deep sleep current
– Wake up from GPIO interrupt, timer, ADC measurements, capacitive touch sensor interrupt

* – not all of the interface pins of the ESP32 module are accessible through the development board
* – this is a 3.3V device, make sure you use level shifter to connect I/O ports to higher logic level like 5V

    Posting in case this helps anyone else – it had me stumped and I was concerned there was a problem with the boards. When using Arduino IDE (1.8 or 2.0 beta) on MacOS, using the ESP 32 Dev Module board profile, I was unable to upload a sketch and kept getting an error “A fatal error occurred: Timed out waiting for packet header”. This was resolved by changing the default upload speed from 921600 to 460800. With that change – everything seems to be working great and the upload speed is still very fast.

    + PROS: Price, form-factor, build quality, built-in battery connector.
    - CONS: The method for reading the battery voltage using the "built-in" ADC pin that worked on the TTGO T-Display is not working on this board. I plan to use this to replace those units in some projects so I'm hoping I can solve that issue.

    Love the price performance ratio. Look at the features you get for the price. Easy to program in C or Python. Pity that the stock is so limited.

    + PROS: HAs everything one needs for most applications in terms of connectivity, A/D ports, Flash and RAM size among others.
    - CONS: Board would benefit from an external antenna connector. Would benefit from have an I2C IO Extender. Limited stock

    We usually keep stock for at least 2 months. But with the slow down of the supply chain, we are not always able to stock up fast enough.
