| Category | Winner | Why |
|---|---|---|
| WiFi Capability | ESP32-C6-DevKitC-1 | The C6 has WiFi 6 (802.11ax) with Target Wake Time for power-efficient always-on connectivity. The H2 has no WiFi radio at all. If your device needs any internet access, the C6 is the only option between these two. |
| Mesh Networking (Thread/Zigbee) | ESP32-C6-DevKitC-1 | Both support Thread and Zigbee 3.0 via 802.15.4 radios. The C6 wins because it can act as a Thread border router (bridging Thread mesh to WiFi), while the H2 can only be an end device or router within the mesh — it needs a separate border router for internet access. |
| Power Efficiency | ESP32-H2-DevKitM-1 | The H2 runs at 96MHz versus the C6's 160MHz, drawing less active power for simple mesh communication tasks. While the C6's deep sleep (7uA) is actually lower than the H2's (8uA), the H2's lower active power consumption from its absent WiFi radio makes it more efficient for battery-powered mesh sensors that wake frequently. |
| Processing Power | ESP32-C6-DevKitC-1 | The C6 runs at 160MHz with 512KB SRAM and includes a secondary low-power RISC-V core at 20MHz. The H2 runs at 96MHz with 320KB SRAM and no secondary core. For any compute-intensive task beyond basic sensor reading, the C6 has a clear advantage. |
| BLE Version | ESP32-C6-DevKitC-1 | Both support BLE 5.3, but the C6's additional WiFi radio means it can handle BLE provisioning, WiFi data upload, and Thread mesh communication simultaneously. The H2 handles BLE and 802.15.4 only, which is sufficient for device provisioning and mesh operation. |
