The ESP32-PICO-KIT is a mini IoT development board with WiFi and Bluetooth. With a size of 52x 20.3x10mm, the module integrates a 4 MB SPI flash and a USB-UART Bridge circuit, allowing developers to connect the board to a PC’s USB port for downloading and debugging.
Featuring a compact body, robust performance and low power, this product is well suited for any space-limited or battery-operated applications, such as wearable electronics, medical equipment, sensors, and other IoT products.
At the core of this board is ESP32 chip, which is a single 2.4GHz WiFi and Bluetooth combo chip designed with TSMC’s 40 nm ultra-low power technology.
The ESP32-PICO-D4 integrates all peripheral components seamlessly, including a crystal oscillator, flash, filter capacitors and RF matching links in one single package. Given that other peripheral components are involved, module welding and testing are not required either.
For easy interfacing, all the IO signals and system power ESP32-PICO-D4 are led out through two rows of 20×0.1” pitch header pads on both sides of the development board. To make the ESP32-PICO-KIT easier for Dupont wires, 2 ×3 header pads grouped on each side of the board besides the antenna are not populated and may be populated later by the user if required.

ESP32-PICO-KIT Development Board
Arrived very well packaged. No damage.
First time using ESP32 DEV KIT 4, I am used to Arduino and RP2024 systems, so the normal ESP32 dev-kit 4 speed is about what an over clocked pi Pico maxes out at. (I don't like over clocking as it seriously shortens the life span of the processes, but sometimes it's a means to an end when high clock per a core is needed). So although program flashing was a little bit more involved than say the Arduino and RP2024 IDE I think I will move to the ESP for the higher performance requirements (keep the 2040 and Arduino for basics).
Yes they are more expensive than Arduino and RP2024 but you do get a lot for your cash in a microcontroller. I might have a go at running realtime Control on one or two of these esp's and off load non realtime to an SBC like Pi or Jetson, inset of the lower performance units, expecting great things
Installed the ESP32 programming tools (I needed a python based tool which ran on Ubuntu to flash rather than an IDE) all good.
I had to blow the voltage select fuse to fix at 3v3. Flashed straight after the voltage, with image I had.
Up and running and correctly partitioned.
240MHz dual core not over clocked, with BT and WiFi. Bonus.
It came with the male headers installed. I needed to add another six for access to SPI ram chip. Otherwise no other requirements.
Used for a retro emulation system of 8 bit computer from 70's. Work's perfectly. (I wasn't the creator of the firmware here)
Perfect.
Thank you....
Harvey.
