ESP32 C61 Block Diagram

Espressif has announced the ESP32-C61 SoC, a new ESP32-Cx chip with improved wireless connectivity, and expanded memory options. The ESP32-C61 builds upon the foundation laid by previous ESP32-Cx chips, such as the ESP32-C2 and ESP-C3, and its specifications appear to be quite similar to the ESP32-C6 launched in early 2023, but this SoC also adds support for the BLE Mesh 1.1 protocol and Quad SPI PSRAM at a frequency of up to 120MHz. It supports WiFi 6 on two modes (802.11ax and 802.11b/g/n) and includes a Bluetooth 5 (LE) radio with support for long-range operation through advertisement extension and coded PHY. The TWT (Target Wake Time) feature is supported in 802.11ax mode to save power, as well as OFDMA (Uplink/Downlink) and MU-MIMO (Downlink) for a high-quality, low-latency connection between devices. ESP32-C61 specifications: CPU – Single-core, 32-bit RISC-V microcontroller that can be clocked up to 160MHz Memory: 320KB on-chip SRAM 256KB […]

WeAct ESP32H2-N4 – A $6 Bluetooth 5.2 LE, Zigbee 3.0, and Thread development board

WeAct ESP32-H2 development board

WeAct ESP32H2-N4 is a low-cost ESP32-H2 development board with Bluetooth 5.2 LE, Zigbee 3.0, and Thread connectivity with a design very similar to the one of Espressif Systems’ ESP32-H2-DevKitM-1 development board, but sold for just $5.70 plus shipping. The ESP32-H2 wireless microcontroller is basically the little brother of the ESP32-C6 without WiFi and aims at low-power nodes in short-range IoT networks. We have previously seen it in Espressif hardware like the aforementioned ESP32-H2-DevKitM-1 and the ESP Thread Border Router board combining ESP32-H2 & ESP32-S3 wireless chips, but so far not in third-party boards, and WeAct ESP32H2-N4 changes that. WeAct ESP32H2-N4 specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh and 802.15.4 (Zigbee/Thread/Matter) radios.
