Rockchip RK3328 (64bit quad-core A53), 1/2/4 GB 1866 MHz LPDDR3 RAM, eMMC socket, 128 Mbit SPI FLASH, Gigabit ethernet, 2x USB 2.0, 1x USB 3.0, microSD card slot... that's a short description of parts of ROCK64...
Very short news.
This tutorial how to use MicroPython on ESP32 is written for Windows OS, but changes in steps will not so difficult for Linux or MacOS.

Let's try it, steps on https://techtutorialsx.com/2017/05/20/esp32-micropython-support/

Olimex released a new single-board computer - A64-OLinuXino. THe development of board started since 2015, now is available on store.

A64-OLinuXino is available in three variants. On store is only A64-OLinuXino-1G4GW now.
A64-OLinuXino-1G0G: The first, the cheapest (40 EUR), contains 1GB RAM, doesn't include FLASH eMMC memory and WiFi&BLE connectivity as well...

M5Stack - stackabled development boards, which be useful for your development. This is description of M5Stack project in one sentence.

The main advantages of M5Stack are Arduino IDE library, whole project is opensource and M5Stack supports LCD.

The device contains one main board, now is it ESP8266, LoRa modul and 2" LCD.
You can buy a lot of boards to Core. For example wave generator and logic analyzer...

UP board or UP² (UP squared) board, these are familiar names of single-board computers.
UP team comming with kickstarter campaign for a new single-board computer called UP core.

UP core is designed for using a lot of GPIO's and peripherals, it contains 100-pin expansion board.

The processor is Intel® Atom™ x5-Z8350 (QuadCore 1.44/1.92Ghz 64 bit CPU), UP core comes with 2/4GB RAM, 32GB/64GB eMMC 5.0, 2 x USB 2.0 connected to pin header, USB 3.0...

SinoVoip company released a few pictures of BananaPi-T3 (BPI-T3). It should be designed for automotive application. Maybe infotainment (?).

UPDATE: BananaPi-T3 will not be on stock for hobby makers. T3 will be only customized for customer.

We can see a few info from pictures which are below. The processor is Allwinner T3 (quad-core Cortex-A7, and Mali400 MP2 GPU)....

We shared a few weeks ago the news about STM32L4 IoT development board. There are pictures of the board.

Olimex - ESP32-EVB.

You can find ESP32 WiFi&BT module built-in arduino programmer (USB-UART bridge), 100Mbit interface, microSD card slot, two relays (10A/250VAC), CAN interface

Other article about ESP32, with using of development board of SunDuino ESP32 and temperature/humidity sensor Si7021 (HTU21).

You can find up a lot of development boards for ESP32 on internet, some are cheaper, some more expensive.
The one czech hobby group (Robotika Brno - CZE) designed universal dev board for ESP32 (WiFi&BT).
The board called RB3200-ESP32universal contains Arduino uno rev.3 connector, power supply - 5V (USB) also 3.3V available on pin headers, LEDs, USB-UART bridge - CP1202 and a lot of pin headers for your sensors...
With ESP32 we can expect a lot of interesting board for wireless connections - WiFi and Bluetooth.
We expect that the Wemos name on the board is maybe abuse of name.

There are two of them. The first dev board contains ESP32, battery holder for 18650 battery, microUSB connector.
The price is $10.29 https://www.aliexpress.com/item/WEMOS-WiFi-Bluetooth-Battery-ESP32-development-tool/32814163663.html...

Friedlyarm released a new version of NanoPi single-board computer - NanoPi M2A.

NanoPi M2A is a new generation of NanoPi M2 by FriendlyElec, the new board responds to customer requirements.
NanoPi M2A combines NanoPi M2 and NanoPi M3.

The processor is the same like M2 Samsung Cortex-A9 - S5P4418 - quad-core up to 1.4GHz. Instead of M2, M2A contains WiFi 802.11 b/g/n and Bluetooth 4.0 module with internal antenna and connector for external antenna as well as NanoPi M3.
