I’ve been playing with several ESP32 boards over the months, and tried several firmware images. I started with a tutorial for Arduino Core on ESP32, a few month later I tested ESP32 JavaScript programming with Espruino on ESPino32 board, and recently Espressif Systems sent me ESP32 PICO core development board powered by their ESP32-PICO-D4 SiP, and while I took some pretty photos, I had not used it so far. So I decided to go with yet another firmware, and this time, I played with MicroPython on ESP32, and will report my experience with basic commands, controlling GPIOs, and WiFi in this getting started post. Flashing Micropython Firmware to ESP32 Board Source code is available on Github, as a fork of MicroPython repo as ESP32 support has not been upstreamed yet. We could built the firmware from source, but there’s also a pre-built binary which you can download on MicroPython website. […]

This TTGO Board Combines ESP32, LoRa Radio, and OLED Display for just $10
Just one year ago, it would cost around $15 to $20+ to get an ESP32 board, that is if you were lucky/fast enough to order one one before it went out of stock. Since then, availability is no longer an issue, and you now can get an ESP32 development board for as low as about $7, or even around $4 during promotions. Today, I was made aware of another board sold under the “TTGO” brand, that includes not only ESP32 WiFi and Bluetooth SoC, but also a (433 MHz) LoRa radio, and an OLED display. Price? Just $10 plus shipping ($1.75 here). TTGO ESP32/LoRa board specifications: WiSoC – Espressif ESP32 Storage – 32MB on-board flash (or maybe just 16MB?) LoRa Semtech SX1278 with u.FL connector + 433MHz antenna (N.B.: Antenna must be connected during use or the Semtech chip could be damaged) Sensitivity” ~ -148dBm; output power: +20dBm Display – […]
