For most IoT projects, the best development kit is the one that supports the radio protocols, power profile, and expansion hardware you need to test—and uses a chip and software stack you can carry into production. A kit lets you check sensors, firmware, wireless behavior, and app or cloud connections before committing to a custom board. ESP32 and Nordic kits are both capable; their protocol coverage and prototyping features make them suited to different experiments.
What an IoT development kit helps you prove
A development kit combines a target system-on-chip (SoC) with practical hardware for experimentation: power and USB circuitry, accessible GPIO and common buses, debug access, and a reference design. Its SDK and examples provide a starting point for firmware. Together, these pieces make it easier to repeat early tests and isolate whether a problem lies in the radio, sensor wiring, firmware, or application connection.
A kit is a validation platform, not a finished product. It helps you learn whether a design direction works before you invest in a custom PCB; it does not by itself establish that the final product will meet its power, size, radio-performance, or regulatory requirements.
Compare kits by the requirements that shape your prototype
Radio and protocol coverage
Start with the networks your device must use. Wi-Fi is relevant when a product needs direct network access; Bluetooth Low Energy (BLE) is common for nearby devices and phone setup; Thread and Zigbee use IEEE 802.15.4. Cellular or proprietary 2.4 GHz requirements narrow the choices further. A board cannot validate a protocol its radio and software do not support.

Power and form factor
USB-powered boards are convenient on a workbench. If the intended device is a battery-powered sensor, look for a kit and SoC that let you investigate low-power operation in a form factor closer to the deployment target. A bench kit can demonstrate functionality, but its power circuitry and peripherals may differ from a later custom design.
I/O, expansion, and debugging
Exposed pins and familiar expansion headers reduce wiring friction when trying sensors, displays, or add-on modules. Check that the board provides the interfaces your parts require, and consider how you will flash, log, and debug firmware. SDK examples, build tools, RTOS support, and debug access all affect how quickly you can move from wiring to a working test.

Software and production migration
Choose a platform whose SDK, security features, and reference design can support the eventual product—not just a quick demonstration. A custom board may need different power circuitry, pin assignments, antennas, or peripherals, so plan to revalidate the design after migration.
ESP32, nRF52840 DK, and Thingy:52 compared
| Kit or platform | Documented radio and protocol scope | Expansion or sensor focus | Best fit for early evaluation |
|---|---|---|---|
| ESP32-H2-DevKitM-1 | Bluetooth Low Energy and IEEE 802.15.4; the board can support experiments involving Thread, Zigbee, or related 802.15.4 technologies, subject to software and configuration. | All pins exposed, according to Espressif’s user guide. | Connected sensors and standards-oriented prototypes where BLE and 802.15.4 matter. |
| Nordic nRF52840 DK | BLE, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT, and proprietary 2.4 GHz applications, according to Nordic’s product page. | Arduino Uno Rev3 form factor for plug-in modules. | Low-power, multi-protocol firmware evaluation and expansion-hardware testing. |
| Nordic Thingy:52 | Bluetooth connectivity to phones, laptops, tablets, Raspberry Pis, and similar devices, as described in its documentation. | Compact, power-optimized kit with multiple sensors for environmental data. | Demonstrating a sensor-led concept, such as environmental monitoring, with a connected app or cloud destination. |
When an ESP32 kit is the right starting point
Espressif’s DevKit catalog includes multiple ESP32 boards, so select a specific board by its SoC and required radios rather than treating the family as a single specification. For BLE and IEEE 802.15.4 experiments, the ESP32-H2-DevKitM-1 is a concrete option: Espressif describes it as an entry-level kit based on a combo module and says all pins are exposed in its user guide.

For firmware, Espressif calls ESP-IDF its official IoT development framework for the ESP32, ESP32-S, ESP32-C, and ESP32-H SoC series. The framework documentation describes more than 100 examples covering components, hardware peripherals, and features. That makes the examples a useful route into a production-oriented C/C++ workflow, but check the framework and example support for the exact chip and protocol combination in your project. See ESP-IDF documentation and Espressif’s ESP-IDF project.
When Nordic’s nRF52840 DK or Thingy:52 makes more sense
Choose the nRF52840 DK for protocol breadth and expansion
Nordic describes the nRF52840 DK as a single-board kit for BLE, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT, and proprietary 2.4 GHz applications. Its Arduino Uno Rev3 form factor can simplify trials with compatible plug-in modules. Nordic documents a USB input supply range of 1.7 to 5.0 V; this is the documented input range, not a statement about a project’s operating current or battery life. Consult the product page and user guide for board details.
Rank #4
Choose Thingy:52 when integrated sensing is the priority
Thingy:52 includes multiple sensors in a compact, power-optimized kit. Its documentation describes collecting environmental data and sending it over Bluetooth to devices such as phones, laptops, tablets, and Raspberry Pis, or onward to an app or cloud service. That integration can shorten the path to a demonstrable sensor prototype; it is a different starting point from a board chosen primarily for attaching and evaluating external modules. See the Thingy:52 documentation.
A practical kit-selection process
- Write down the required radios. List the protocols the prototype must test—such as Wi-Fi, BLE, Thread, Zigbee, or another supported option—and verify them for the exact board, not just the product family.
- Match the test to the deployment. Note whether the device will be USB-powered or battery-oriented, and whether a compact integrated sensor kit or accessible expansion headers are more useful.
- Check the interfaces and tools. Confirm the GPIO and buses required by your components, then verify the SDK, examples, build tools, and debug method you expect to use.
- Plan for the custom board. Prefer a kit whose SoC, SDK, security capabilities, and reference design can carry into the intended product. Record any changes to pins, power, antennas, or peripherals that will need fresh validation.
- Confirm the exact board and availability. Espressif’s DevKit catalog lists multiple boards and shows Amazon as a purchase channel for the ESP32-H2-DevKitM-1. Check current seller, revision, and availability before ordering.
What development kits cannot tell you on their own
Successful firmware on an evaluation board is evidence that a prototype path is workable, not proof that a finished product is ready to ship. The custom PCB can change antenna behavior, power consumption, component interactions, and physical layout. Re-test the radio, energy use, sensor readings, and application connection on the hardware that represents the product. Also verify the SDK and protocol implementation for the precise SoC and software versions you intend to use.
